Tecnifibre HDMX 16 Playtest



Tension used for playtest:
52 lbs.

Regular string setup & tension:
Yonex Poly Tour Pro at 50 lbs.

Racquet used for test:
Dunlop AG 200

Power/Control of test string:
This was a low powered multifilament string. I have not played with such a low powered multi in the past. I think this would make for a great transition string for those switching over to poly or switching from poly to a multifilament string.

Control was good for a multi as it was low powered. I am however used to poly strings and taking full cuts at the ball so I had to make adjustments with my swing. I was hitting the ball longer at first, but after playing for 15 minutes I adjusted.

Feel of test string:
It felt very comfortable to me. On clean hits it felt crisp and responsive.

Spin:
Spin was not its forte. It isn't a polyester string so that was a given. There wasn't that snapback you would expect from a polyester string. But that said, with its coating there was some snapback and with exaggerated take back, I was still able to impart some spin on ball.

Durability:
Good for a multifilament. I haven't seen a lot of fraying or notching and I am at the 6 hour mark. I am using 18x20 pattern and that definitely helps with string durability. I'm a solid 4.0 for reference.

Playability Duration:
The initial tension drop did not feel that much. Off the stringer and from first hit till initial two hours the stringbed played very consistent. I felt the power increase after the two hours probably because of more tension drop and coating wearing off. At the 6 hour mark and the playability has stayed consistent.

Tension Recommendations:
I think I made the right decision to not string it too tight. This string is not very powerful for a multi. If I restring it again, I will string at same tension. Maybe a couple pounds tighter if I hybrid it with a poly string, just for more control.

List any additional thoughts
Here are a couple of thoughts:
  1. Really liked the color. It is a refreshing change from the monotonous black and whites of strings.
  2. From a playability perspective I would definitely recommend this string to those looking to transition to polyester strings from multifilament or natural gut. And for those poly users looking for more comfortable option that still is a bit low powered like a poly.
Overgrip Questions:

Likes/Dislikes:
Great quality. Lasted long enough for multiple use. I sweat a lot and it had great sweat absorption. Better than leading Wilson Pro and Yonex Super Grap IMO. No dislikes in this playtest.

Would you consider using regularly?
Yes. I liked it a lot and I will definitely consider switching to it.

Finally, a great big thank you to Tennis Warehouse @TW Staff for this playtest opportunity. Truly appreciated.

Which overgrip is it? As in what's the name? And is it a new offering? I've tried the Technifibre Pro Contact and really liked it but never switched. I've been a Wilson Pro user for a long time but after reading everyone's feedback, I might buy some to try. Is it more like the Super Grap/Wilson Pro type, or drier clothy Tourna/Lux Dry Elite kind?
I am currently using Yonex Super Grap. I took pictures of my setup; however, I don't know how to insert pictures.

For pictures you will need to go to an image hosting website (like imgur.com or imgbb.com) and upload photo there. Then provide the link over here on this forum. There is a button on top right where you can put that link from the image hosting website. It is pretty simple once you get a hang of it.

Tension used for playtest---55 lbs.

Regular string set up and tension---Head Rip Control 17, at 57 lbs.

Racquet used for test---Prince Graphite Classic 100.

Power/Control of test string---like others have said, it's more powerful than your usual poly. But I'm not used to a 16 gauge string, so it was alittle tough to control.

Feel---pretty crisp and somewhat comfortable. I'm glad I didn't string it any lower.

Spin---so-so. I'm so used to 17 gauge strings to create spin. I'd gladly try this stuff in a 17 gauge anyday.

Durability---looks like a very tough string so far. I'm a 4.5, but not a string-breaker. Hasn't notched yet.

Playability duration---had to put more topspin on it to produce results.

Tension recommendations---when I try this string again (hopefully in a 17 gauge), I'd stay at 55 lbs. (When I try a full poly string, it's at 52 lbs.)

Additional thoughts---I love decent 17 gauge multis, like Rip Control and Intellitour---I don't like full poly or any hybrid setup so far. I can't wait to try HDMX in a thinner gauge. It would probably kick ***.
The next step in the string industry is, obviously, to create a decent poly/multi hybrid in one string, and I think the smart folks at Tecnifibre have done that. Bravo.

Tecnifibre overgrip---I usually use Tourna Mega-Tac. This TF Pro Contact is surprisingly very similar. I'd buy a 12-pack of this stuff anyday. 10 thumbs up!!

(Thank you, TW, for the opportunity of this playtest!)

After a x2 sets of doubles and a round of live ball there isn't any notching. The crosses however on certain parts looks like the coating is peeling.

Tecnifibre HDMX 16 playtest.

Tension
52 pounds

Regular String Typically a hybrid of Poly and Synthetic Gut. I tend to experiment a lot, but usually go cheap for everyday use with something like Prince Tour and Wilson Synthetic Gut.

Racquet Yonex VCORE 98

Power 5/10 I was surprised how low powered it was considering how the string physically felt. Much softer feel than the plastic feel of a polyester string, but similar power to a polyester. I have the same racquet strung at the same tension with polyester, and HDMX was more powerful, but not by a lot.

Feel Comfortable. Great soft feel. Not nearly as harsh on the arm as a polyester string.

Spin 7/10 I was able to generate quite a bit of spin compared to my usual setup. This string seemed to give me the perfect combination of control and power which allowed me to take a full swing to generate more spin.

Durability I got about 30 minutes of doubles playing(only used it for serve games as noted in the grip review), and then 1 hour of singles before it broke. That is about typical for when I use syn gut or multi strings. As somebody earlier mentioned, it was the crosses that started to fray. One of the crosses started fraying, and about 20 minutes later it was done. Other strings were beginning to fray, so they wouldn’t have lasted much longer either.

Playability Duration It was great until the last 3 minutes. String frayed badly, it got loose and control dropped for a few minutes and then it snapped.

Tension Recommendations I would string it at 52 again, or slightly lower(51 or 50). I wouldn’t go higher since it was pretty low powered and I worry about the arm if it was higher.

Additional Thoughts: First off, it was a great string for stringing. More maneuverable than polyester and easy to weave. For me, it was a great string while it lasted. I was getting great depth and spin based on the control of the string allowing me to take full swings, but having a bit more power than polyester. I would love to hybrid it with polyester at about 50 and see how it plays. My only concern is that I did end up breaking the cross string. I would definitely prefer this string over syn gut because of the control, and I would use it over poly except for the durability.

Tecnifibre Overgrip I am the wrong person for this overgrip. I’ve used tournaGrip since juniors and I sweat a lot. I use Wilson Pro during the colder months and really like that one when sweat isn’t an issue. It took a very small amount of sweat for this to lose its tackiness and because quite slick. I actually only used it for my service games in doubles, because I couldn’t keep it dry enough for full use, and then switched it in warmups of singles. For people that don’t sweat much or for the colder months, I would think this would be an ok overgrip.
 
Tecnifibre HDMX 16 playtest.

Tension
52 pounds

Regular String Typically a hybrid of natural gut mains (Babolat Tonic 1.35mm) and poly crosses (Tier One Ghost Wire 1.28mm). I usually have 3 identical racquets (Yonex Ai98) with two strung with gut/poly and one with full poly for wet conditions. I string my poly strings below 50lbs in a full bed. I strung my new-to-me Prince Textreme Tour 310 for this playtest. I used the HDMX in mains and my regular Tier One Ghose Wire in the crosses since lots of playtesters mentioned low spin in a full bed.

Racquet Prince Textreme Tour 310 (just picked up this racquet used and it was originally strung with Tecnifibre Ice Code).

Power 6/10 I thought it had more power than the full poly setup that was in this racquet before (Ice Code). It was less powerful than my regular gut/poly setup, though it's not an apples to apples comparison since I have yet to try gut/poly in the Prince.

Feel 7/10 Pretty comfortable with softer feel than full poly. Felt solid on impact and didn't seem to jar my sensitive shoulder.

Spin 6/10 I was able to get a decent amount of spin in this hybrid, nothing spectacular. I don't think someone should go to this string if massive spin is required for their game. I found the spin adequate, but at times I had to actively think about putting extra spin on my strokes to keep the ball from going long. I don't have this issue with gut/poly or full poly. The upside of this is I was getting good depth on my strokes more easily. If I played with the string longer this might end up working really well for my game since I often over-spin some of my strokes and leave the ball short.

Durability 3/10 I only got about 2-3 hours of singles in before I snapped the HDMX mains right in the sweet spot. For me, this is not durable enough for me to consider using. I get 20+ hours on a lot of my gut poly setups. I also rarely ever break full poly and usually decide to cut it out at about the 8-10 hour mark.

Playability Duration 8/10 I didn't notice any major change in playability for the short time I hit with it before it broke. If there was a large drop in tension, I didn't feel it. Power level and spin seemed to remain consistent before it snapped on me. My rating here shouldn't carry too much weight because I broke these strings so quickly.

Tension Recommendations I would probably string it at 52 again, maybe a pound or two higher if I did a full bed. Don't think I'd go any lower as power and comfort were already pretty good at 52.

Additional Thoughts: I string all my own racquets and this was very easy to string. I liked the color of the string a lot. It looked great in my Prince racquet that has a lot of green in its paint job. I don't think it offers enough of anything for me to switch from my normal natural gut mains. When used as a main, gut beats it in durability, power, and spin
(at least when crossed with a smooth poly cross). For some frame of reference, I'm a 4.5 baseliner with a spinny forehand and rather flat two-handed backhand.

Tecnifibre Overgrip Right before I got selected for this playtest I replaced all the overgrips on my racquets with my normal Yonex Super Grap. I will be sure to report back when I get a chance to try out the Tecnifibre overgrip. It sounds like it will be the type that I like, tacky and absorbent.

**EDIT: Ok, got a chance to try out this overgrip. I did not care for it coming from many years of using SuperGrap. First issue was the length. It was much shorter than the Yonex grip and didn't quite reach all the way up. I usually wrap Super Grap and trim a little at the top. It's always better to have a little too much versus not enough. Second issue, the grip had a very plasticky feel to it. I have very sweaty hands and this grip felt very slippery to hold when my hands were pouring sweat. Even when saturated, the Yonex grip never feels like wet plastic like this Tecnifibre did. I'll stick with Super Grap.

***Thanks again for including me in the demo. I really appreciate the opportunity.

Tension(s) used for playtest: 58lbs, strung on my Gamma X-2

Regular string set up & tension: I experiment a lot with strings so haven't found my go-to yet. Currently my favorite is Head Lynx 17 at 53 to 55 lbs

Racquet used for test: Yonex EZONE DR 98

Power/Control of test string: Definitely higher than a typical poly but much lower than a typical multi. Comparable to Head Velocity which is another multi I like

Feel (Stiff? Mushy? Muted? Crisp? Comfortable?): Very comfortable as you'd expect from a multi but not too mushy to the point where you can't feel the ball. Combined with a flexy racket like the EZONE DR it was definitely a very comfortable hitting experience.

Spin: Better than most multis but of course not as much as a poly. I definitely felt like the spin deteriorated over the playtest as I eventually had trouble keeping balls in unless I started to force the spin on my strokes.

Durability: I've played about 4 hours on the string so far and it looks like it will break any minute. My crosses in the sweetspot are heavily notched and are barely hanging on. I'm a heavy spin player so I tend to break non-poly strings pretty quickly.

Playability Duration: It looks like I'm going to get 5 hours max on the string so can't complain about the playability duration seeing as its been very playable the whole time. Definitely starting to launch more balls though as the strings are about to break. One thing I liked is that the string movement was way better than other multis and synguts I've tried in which I constantly have to adjust strings so that they're straight.

Tension Recommendations (would you string it differently next time - why): I'd keep it at the same tension, maybe a couple pounds higher if anything.

List any additional thoughts (optional): Nice string, I'd consider using it in a hybrid with a poly. I probably wouldn't play with it in a full bed as it would probably be too expensive and not durable enough for me.

EXTRA CREDIT - overgrip question

I liked the feel of the overgrip and definitely would consider using it. It's very cushioned, tacky and also seems pretty durable. Only problem I had was that it got very slippery when wet. My hands don't typically sweat much, but in hot conditions my body will be sweating so much that sometimes sweat from my face will drip onto my racket and grip. When that happened I had serious trouble keeping a grip on my racket.

Thanks to Tecnifibre and TW for the opportunity!

Tecnifibre HDMX Playtest
  • Tension(s) used for playtest
I strung it at 52lbs with a 10% prestretch. I wasn't certain if I should prestretch or not as its a multi...with poly fibers, but in the end I decided to give it a try.​

  • Regular string set up & tension
I've been bouncing around with strings lately, but for the last month I've been using Laserfibre Native Tour 1.25 at 50lbs w/ 10% prestretch.​

  • Racquet used for test
Yonex VCORE 98 Galaxy Black​

  • Power/Control of test string
Definitely on the low side for a multi. Honestly I'd say it was very close to my current poly, with maybe a little more 'pop'. But with this comes a lot of control. I never really felt like I was tempering my swing, yet I also didn't feel like I was overhitting much, if at all.​
At the net it felt really nice. Good pop & control off the volleys, and a bit more touch than my normal string. I find sometimes its hard to hit touch/angled drop volleys with full poly. I hit a few in my doubles matches that felt 'natural'.​

  • Feel (Stiff? Mushy? Muted? Crisp? Comfortable?)
I'd say its a combination of muted and comfortable. No twinges at all over 2 singles and 2 doubles matches. As I mentioned above, touch shots at the net felt really nice. Good pocketing.​

  • Spin
I don't hit with much spin to begin with, but it felt as if I had to work a little harder to get the ball up & down. However, due to the lower power, it resulted in my shots lander deeper, but not overhitting. I was able to generate some decent kick on my 2nd serve, but again, I felt like I as working a tad more to get the same RPMs as full poly.​
It is interesting as I never really had to straighten the strings after points (as I remember years ago w/ synthetic gut). So I'm guessing the 'poly' aspect of the string gives it a bit of 'snapback'.​

  • Durability
Since my strokes are fairly flat, I'm not prone to breaking strings, but after only approx 6 hours of play (3 of them doubles), I noticed the beginning of fraying. I presume high school/college type players would break this fairly quickly.​

  • Playability Duration
While after 6 hours it is starting to show signs of fraying, its still playing well. I haven't noticed any real drop off in playability from my first shot to my last. Tension numbers below represent (1) immediately off the machine, (2) after my 1st hit, and (3) after the 6 hour mark:​

  • Tension Recommendations
I might want to try this a few pounds looser at 50 just to see how it plays. I have no idea if prestretching had any effect, so I might also try 52 w/o a prestretch.. I'd like to see if someone else used RacquetTune to track their tension over time.​

  • List any additional thoughts (optional)
I think this is an interesting string: I'm not sure if I would qualify it as soft & powerful for a poly, or crisp & low powered for a multi. I would like to try this in a hybrid, using the HDMX in the mains and another smooth round poly in the crosses. It might be a good solution for poly lovers who don't break strings (i.e., me), or multi users who want to try a poly, but have a sensitive elbow. I might also try the 17g.​
Also, the color looks nice in my Galaxy Black frame :)
EXTRA CREDIT - overgrip question
  1. Please briefly list your likes and dislikes of the Tecnifibre overgrip you were sent (ATP Pro Contact White)
    • Likes:
      • Good level of 'takieness' (is that even a word?)
      • Not too thick (0.6mm). On par w/ Wilson Pro & Supergrap
      • Good feel. Some grips have a 'plastic' feel to them.
      • Held up nicely in sweaty conditions
    • Dislikes:
      • Please, please, please...make it a little longer? Some of us have frames w/ longer handles, and like to wrap it around the butt cap twice before going up. Both Wilson Pro and Supergrap make it up my handle after I go around twice.
  2. Would you consider using it regularly?
    • I've actually ordered a couple 12-packs of it. I was low on my Supergrap reel and was looking to try something different. Am happy they sent it along.

------------ Background and Stringing

Tension used for playtest:
55 lbs.

Regular string setup & tension:
Solinco Hyper G 17 x Gosen OG Sheep Micro 16 in the low 50s
Lately I've been experimenting with thicker Gut mains (Klip Legend 16) and cheap poly crosses (Pro's Pro Concept 17), although price/durability has been an issue.

Racquet used for test:
RF97A

Stringing process and string impression:
HDMX strung up just like a synthetic gut, over a higher-quality multifilament that works to mimic natural gut. The coating is probably the cause of this, but it was a simple enough process with no kinking and tie-off were easy.
Not a huge fan of the color, as I prefer the punchier green of Hyper G. It definitely is unique, though.

Hitting duration and description:
2.5 hours, then breakage.
4.5 player with flatter strokes, OHBH
Played mostly singles (sets, groundstroke games) with former D3 Collegiate player throughout the duration of the test

------------ HDMX 16 Performance Review

Power/Control of test string:
Definitely the most low-powered multi I have played by a good margin. Although I don't play with a full bed of multi often (I barely remember the last time), I've never felt this comfortable swinging out on my shots as usual with a multi. Directional and depth control both above average again for a multi, and I felt comfortable keeping my foot on the gas throughout some tight sets of singles. Pretty pleasantly surprised with how it played, and I didn't have too much trouble transitioning from my usual setups.

Feel of test string:
I was getting a twinging, high-pitched response when hitting with the string after the first 15 minutes or so of hitting. It wasn't jarring, but it wasn't pleasant. It didn't seem to affect the way the string played and the bed remained comfortable, but I wasn't a huge fan of the feel of this string. Felt too muted and plastic-y.

I'm usually not that picky when it comes to the feel of strings, but this was a real exception that will prevent me from continuing to use HDMX, at least in a full bed.

Spin:
Although not a spin monster, I was once again pretty pleasantly surprised with the amount of spin I could get from this set. The coating warranted snapback for the duration of the string that certainly helped in rotation generation. Unfortunately, (spoiler alert) that duration of time was pretty short.

Durability:
I got about 2.5 hours with the full bed of HDMX before snapping a central main. There was only a tiny bit of fraying prior to the break, but not as much as on other multifilament (where you can usually predict exactly where the break will occur from fraying). There were a few factors that played into why the durability of this string was so poor, but I've been playing much more singles with some new hitting partners, which was probably the bulk of the reason. Moreover, the last time I played with a full bed of multi was 6 or 7 years ago.

Playability Duration:
Other than the odd feedback I was getting throughout much of the playtest, the string performed well throughout its lifespan, up until breakage.

Tension Recommendations:
I would probably go down a few pounds since the power level was low for a full bed of multi, and to see if that would alleviate the strange feedback I felt throughout.

List any additional thoughts
This was a weird playtest for me. I played some great tennis with the string and it's certainly comfortable with a good power level and decent spin for a multi. However, the feel of this string and poor durability will keep me from using this string in the future. It may be interesting as a cross string in some setups, but I can't justify the use of it over a cheap synthetic gut, which will offer a lot of similar benefits (HDMX would likely offer slightly better main snapback) to using this string as a cross, at a more affordable price point.

------------ Overgrip Impressions and Review

Likes:
Technifibre is no slouch when it comes to detail and quality--their tennis bags are definitely among the best. That devotion to quality is reflected here in this overgrip, too. The tackiness is right where I like and similar to Wilson Pro or Yonex Supergrap, maybe slightly more. The finishing tape is of nice quality and the grip was embossed with branding which I thought was a very cool touch. The packaging for the single grip was very nice and similar to the single-packaged overgrips from Yonex.

Dislikes:
It felt thinner than my usual Yonex Supergrap, and was more prone to creasing during application. The grip is fairly short in comparison to Wilson Pro and Yonex Supergrap, which would be an issue for two-handed backhand players or players who like to wrap over the buttcap multiple times (e.g. I prefer two wraps).

Neutral (?):
The non-tacky side of the grip also felt weirdly sandpaper-like.

Would you consider using regularly?
I liked it a lot, but I think I'll be sticking with my Yonex grips. With the embossed lettering and marginally more tacky surface, I think Tecnifibre has released a competitive detail-oriented product into the crowded tacky overgrip world. They just need to make them a bit longer!



As always, thanks TW!

  • Tension(s) used for playtest 57 lbs.
  • Regular string set up & tension I hit with 2 different set ups, but are similar to a degree. I use Klip Gut uncoated 16g. 63 lbs. and Luxilon Gut 61 lbs.,
  • Racquet used for test Head Radical
  • Power/Control of test string A low powered multi, but that's to be expected of a string that should hit like a hybrid of a multi and poly.
  • Control was great. Baseline heavy hitting had very good control, and a comfortable control with volleys.Was able to get decent spin on second serves very nice with this string!
  • Feel (Stiff? Mushy? Muted? Crisp? Comfortable?) A very comfortable hit, and not as muted as my nat. gut set up.
  • Spin. I hit relatively flat old school style, but was able to generate spin as needed. As stated above, was able to get nice spin with second serves nice with this string.
  • Durability. String lasted approx. 5 hours of hitting. 3 hours of singles and approx. 2 hours of doubles.
  • Playability Duration. Played well for the 5 hours it lasted. Had decent snap back, good control, and a relatively comfortable hit for a synthetic string.
  • Tension Recommendations (would you string it differently next time - why) I woul;d probably go to a lower tension, low 50's to get a little more zip out of the ball.
OVER GRIP REVIEW

Likes: I liked the feel. I typically use a more dryer type over grip, like the Luxilon, or the Wilson Advantage over grip, but using a tackier one like this one, I can get use to it.
Dislike: The Luxilon and Wilson Advantage has little more cushion to it.
I got use to using this grip and would very much consider purchasing it in future.

SteveI: Techifibre HDMX 16 / 1.30 mm Play-Test


Tension(s) used for playtest:
56 / 54 lbs

Regular string set up & tension: I use quite a few set-up and do quick a bit of play-testing for TW and others. My current favorites are Volkl Cyclone 19G and Team LF Vorso 17G. 52 /50 and that also depends on the season.

Racquet used for test: Volkl Quantum Scorcher with mods (11.6 oz 7-8 points HL - 102 head size and 16 x 19 pattern) Flex: 60 RA. Great platform frame.

Power/Control of test string: I am used to using soft and powerful co-polys and hybrids. I found this offering to be lower power than my normal setup and low for a multi. Since this is designed to be a all in one hybrid, the power is about what I expected. I love the new multis like LF Surpreme 2.0, Head Velocity and Bab Origin. Which I have play-tested and used in live matches. This string was in this grouping. The power again was on the lower side but that made the control also better. You could take nice full rips at the ball and it not lose control. I am a spin player so my spin strokes also worked very well with this string.

Feel (Stiff? Mushy? Muted? Crisp? Comfortable?): Crisp and Comfortable in one package. I was not aware of the posted stiffness rating at the time I did the testing but I really loved the feel and it was great on my arm and shoulder. Would love to test this in 17G.

Spin: The spin is what I expected.. not Volkl Cyclone 19G or LF Vorso... but what is? I employ spin in most shots in my game.. and it did not fail me.. but I did have to adjust for the lower launch angle and spin production. Being able to take big rips at the ball due to the lower power helped create a higher swing path and higher launch angle. Spin was adequate.

Durability: I never break strings.. but I popped these at the 7 hour mark. This might be due to me swinging extra hard and ripping up through the ball. The strings were sawing back and forth so I am sure that was cutting string life down.

Playability Duration: For the 7 hours in my frame I really thought it held up well. Compared to TF x-1... it was very stable. I compare this to Head Velocity and LF Supreme 2.0. Solid and stable. My strokes did not have change in the 7 hours to adjust to tension loss.

Tension Recommendations (would you string it differently next time - why): I was very happy with my tension but I read a few of the comments and reviews to try to get as close as possible to the correct tension for my game. Having only one set to test and really missing the mark can just make the playtest a waste of time in my book. I would have to adjust the tension based on weather conditions as one might do with any other setup. Thanks to the comments in this thread.. I had a good feeling for a starting tension and thus a enjoyable playtest.

List any additional thoughts (optional): Really loving these next gen Multt/poly offerings. These are perfect transition strings for player moving to different types of strings without major adjustment and arm injury. Great job to those companies offering this new and improved products! String was also a dream to string..


EXTRA CREDIT - overgrip question

1. Please briefly list your likes and dislikes of the Tecnifibre overgrip you were sent. It was pretty perfect for me. Not too thick... nice and tacky and held up well. I like black overgrips... Love to see this in black and red.

    • No regular string set up but often play with a shaped/rough poly or good old synthetic gut. For MP racquets I use 50-52# for synthetics and 43-48# for poly
  • Racquet used for test
    • Angell TC95 63RA 16x19
  • Power/Control of test string
    • Medium power level overall. The flight trajectory was on the low side and with the lack of spin compared to a poly, the ball would land fairly deep in the court.
    • Control was excellent and almost poly like once you get dialed in on the lack of spin compared to a poly
    • For a mutli, it’s rare for my game to have a point and shoot string to hit my spots with a flat shot. I was able to do this more often with some adjustment.
  • Feel (Stiff? Mushy? Muted? Crisp? Comfortable?)
    • Not as crisp as a synthetic but fairly good for a coated multi
    • Comfort was good and would be great for a poly player suffering from arm issues
  • Spin
    • For the type of string this is I was able to produce a good amount of spin. I had to work a bit harder to do so compared to playing with a smooth or textured poly. I was happy with the amount of spin I was getting from this and could adjust to this string.
    • Spin in either my slow kicker or faster kicker was excellent. The trajectory had a nice arch and bounced up nicely that a few times I caught my opponent in my favor.
  • Durability
    • The coating on the crosses started fraying on the first day. The mains had notching but didn’t look frayed as well. This seems to be a more durable string compared to other multi strings for my type of game and current condition
  • Playability Duration
    • Playability was predictable for the first couple games. When the crosses started to fray the snap back reduced and the playability changed. It wasn’t so much that it would be a deal breaker for me. Tension maintenance seems to be good, but the observation was just by feel. I did not use Racquet Tune or a tension-meter
  • Tension Recommendations (would you string it differently next time - why)
    • I would like to try it a bit lower to see if the spin or power would increase. I was happy still using my tension range I use for synthetic/multi strings
  • List any additional thoughts (optional)
    • I am a recovering Aortic Dissection Survivor of just 6 months. I’m finding my game again but my endurance is low as well as my strength. I don’t feel I’m hitting the ball as hard and with the lack of exercise I feel the uphill battle. I seemed to have hurt my wrist by lifting or moving something, so it bothered me for a little while during string test. I usually write my review on the deadline of the test or when strings break but choose to write one now since I’ll probably take some time off to let my wrist heal.
    • I think that this string would be a great option to those wanting a softer option from poly but wants the control of poly along with decent spin.
    • This string might also be a great offering in a hybrid with a smooth poly in either the mains or the crosses.
    • This string was easy to string
    • The color was great
    • THANK YOU Tennis Warehouse and Technifibre for letting the tennis fanatics be a part of this
EXTRA CREDIT - overgrip question


  1. Please briefly list your likes and dislikes of the Tecnifibre overgrip you were sent.
    1. Likes – not too thick/spongy. Soft and slightly tacky feel
    2. Dislikes – when I didn’t play with a wrist band on a hot day, the grip would soak up the perspiration and it would get slippery
  2. Would you consider using it regularly?
    1. I’m not sure at this time. It is a consideration as I like how it was thin. If the price was comparable to other OGs of this type, it could be a contender to be in my racquet bag.

Well I put this off as long as I can. I hate to be the bad guy but I didn't get along with this string at all. Here's my take on
Techifibre HDMX 16

Tension strung: 55/53

Regular string set up & tension:
For this Gravity S I've used Lynx and Xperance at 49/48 I liked the way the racquet played and thought a little taste of multi might boost the power. I boosted the tension because the string felt so soft and I didn't want it to powerful. If I go a little tight to start with sometimes it backs into the tension I want as it ages. But you can't make it tighter once done.

Racquet used for test: Gravity S 104 16x20 very nice racquet. I like the feel just could use a bit more pop.

Power/Control of test string: I suspect I started off to high on tension. The string feels so soft in the hand I was expecting multi like spring and power. I feel HDMX plays more like a soft dead low power poly. Because I had strung it higher than I should the large sweet spot and feel on this racquet were shrunk. I ended up compensating for that by swinging harder and swinging harder for more power lead to diminished control.

Feel (Stiff? Mushy? Muted? Crisp? Comfortable?): Definitely not a multi feel like Tecnifibres Multi-feel or Nrg more on the poly side of things. It got softer after a couple hrs. but it never got to a feeling that I liked.

Spin: The spin is not bad but just rather blah.

Durability: I toughed it out for about 6 hrs. till I cut them out. When I cut them they retracted 6 in. and pulled through the grommets like a syn gut so there was life in the string. I just didn't like it.

Playability Duration: I was never happy with the playability. It did improve as they loosed or I adapted more.

Tension Recommendations (would you string it differently next time - why): I would string it like a poly somewhere in the mid 40's to get more power and feel.

List any additional thoughts (optional): Like I said this string and I just didn't get along. I replaced it with Tourna S7 tour at 46/44 and the racquet came back to life power spin feel all the good stuff. I don't have any arm problems and don't use much multi, I am a fan of NG/Poly that is a good feeling combo.

Extra Credit Overgrip

I lean towards the mid tacky grips not dry like Tourn grip or so sticky you can't move your hand on the grip. This one was perfect for that. Not to thick or thin and gave a great feel for the bevels. Definitely one I could use in the future. I do like assortment colors in the 30 packs.

I ended up stringing the HDMX in my 2018 Pure Drive for the playtest. The Ezone 98 is my "regular" racquet and I was just unwilling to switch from poly for our current combo league. I have always WANTED to make the Pure Drive work though just because of the tremendous power and forgiveness you get from it. It causes arm pain with every poly setup though and shreds synthetic gut. Figured this would be a fantastic string to test in it.
  • Tension(s) used for playtest
    • Strung at 54 lbs on an electronic machine at my local club.
  • Regular string set up & tension
    • Have strung everything from full poly at 50 lbs to synthetic gut at 57 lbs in this frame. I would not go lower than 54 with this string in the Pure Drive. My regular string used in just about any frame for league play is gonna be a soft poly. I use either Sonic Pro, Sonic Pro Edge, V-Star, or Cyclone almost exclusively (although lawd knows I've tried almost everything). A full bed of poly is the only thing I really have confidence in, but my arm doesn't always like it.
  • Racquet used for test
    • 2018 Pure Drive. The powder blue wonder.
  • Power/Control of test string
    • Power was low for a multi. Reminded me a lot of Velocity, which I have used pretty extensively. Felt a little more crisp, but honestly the two strings seem to be very comparable to me. I was able to swing out on my forehands for the most part with this string. I have used NRG, Wilson NXT, RIP Control, and Reflex, and it didn't have nearly the rocket launcherness of any of these strings. However, I did not get the control I get with poly. I hit a flatter ball with this string with less spin. Just did not get as much action out of it for the same amount of effort. One big takeaway for me is that the string was low-powered enough to be playable in the Pure Drive in a full bed. That means it is the FIRST full bed non-poly string I have used in the Pure Drive that was truly playable.
  • Feel (Stiff? Mushy? Muted? Crisp? Comfortable?)
    • Muted and crisp. Didn't feel mushy to me at all. After the first hour of hitting the strings settled and I got a just a bit of a trampoline effect. I'm sure it could be adjusted to over time, but coming from the linear response of poly I felt like some control was lost. However (however), there's something to be said for the comfort of this string. It's crisper and doesn't feel like a pillow like RIP control. And I had ZERO arm pain using it in the Pure Drive. Even synthetic gut has given me elbow and wrist issues in the Pure Drive, so it's a pretty big deal in my opinion.
  • Spin
    • Good but not as good as poly. Not as good as a hybrid with poly mains. I never had enough confidence in this string for league play, although I could see it being an excellent alternative if you are forced to completely drop poly due to arm issues. Kinda weird watching slow spinners and knuckleballs fly off my racquet. I will say that it will make spin if you add some extra brush and force it to.
  • Durability
    • Starts off with a very slick coating and no string movement. After the first hour the slickness was a lot more rough and there was some string movement, but not nearly as much as synthetic gut. I am not much of a string breaker, maybe because I don't play nearly enough singles. In any case, I used this string for around 10-15 hrs (mainly doubles with about 3 hrs of singles and rallying added in) and it hadn't broken. After the initial break-in the degradation seems very linear to me, with string movement and a bit of shredding steadily increasing. I noticed that a lot of the reviewers on here are 4.5 and I'm a step below that. I think this string has fine durability for a 3.0, 3.5, 4.0 player. Above that level you're going to run into string breakage issues, just like any multi.
  • Playability Duration
    • It is still playable for me after 10-15 hrs. I'm still using it and will come back on here and let you know when it pops, if I can remember. Seems to hold tension well (much better than poly), although I haven't put racquet tune to it.
  • Tension Recommendations (would you string it differently next time - why)
    • Would go 55 lbs in a Pure Drive/Pure Aero/etc. Would go 52 lbs in a more control-oriented racquet. If you string it up super tight it's gonna feel boardy and I suspect it'll pop sooner.
  • List any additional thoughts (optional)
    • Wanted to really like this string but ... I don't. I'm too used to my soft polys, and there was not enough spin and control for me. If I'm ever forced to go full multi due to arm issues though, this would be a top choice, if not THE top choice. Not sure if I'd pick it for a cross in a hybrid, though, because the feel might be a little too close to poly. I can't see the slick coating lasting a particularly long time in a hybrid. Anyway, this is just rambling speculation, but it seems to me you'd used this string full bed or not at all. YMMV, as they say.
  • EXTRA CREDIT OVERGRIP
    • I wrapped the overgrip up on my Ezone 98 as soon as I got it and took it out for a league match. My usual overgrip is Tourna Blue, but I have used both the Wilson Pro overgrip and Yonex Supergrap. This one has the really nice cushioned and tacky feel of the higher end (i.e. not tourna blue) overgrips. I was pretty stoked. I do play in the dirty south though and we're still in the upper 90s here during the day and this thing was slick as a (metaphor) after the warmup. I had to wipe it off with a towel at every changeover and I was genuinely worried that my racquet was gonna become a projectile on my serve. So unfortunately I went straight home after the match and threw it in the trash, put a tourna blue back on the racquet. Would be a great grip for someone in a drier climate or with less sweaty paws than me, but I can't use it.

Thank you to the @TW Staff and Tecnifibre (@Tecnifibre Official) for this opportunity to playtest this "Hybrid 3D" string.

Tecnifibre HDMX (1.30mm)
*NOTE*: The string arrived in a demo package labeled 1.30mm. The string was printed with 1.30mm. However, the pre-install measurement with a digital caliper averaged 1.356mm (multiple readings across the length of the string). The reading was spot on at 1.30mm on the installed bed measured at various locations on mains and crosses.

Tension(s) used for playtest
25.5M/25.5X in kg
56.0M/56.0X in lb

My usual set up is full bed co-poly or a co-poly/syn gut hybrid. Based on description of composition from Technifibre, I anticipated HDMX would play firmer than Duramix and HDX Tour. As an all-in-one “hybrid” string I chose a reference tension in between that for my full bed co-poly and full bed natural or synthetic gut.


Regular string set up
All 1.25mm in the 22kg +/-1 (48lb) range with Kirschbaum Pro Line Evolution, Tourna Black Zone

Racquet used for test
Dunlop Aerogel 4D 200 Tour (16x18) weighted to 365gm (12.9oz), balance 305mm (12 HL)
This was a very nice string to install and I debated whether to put it in my 18x20 4D 200 instead. I stuck with my usual string playtest racquet – the 16x18 Aerogel 4D 200 Tour.


Overall Rating of test string
9
Awesome! I reserved one overall rating point for when I evaluate feel and playability during cooler weather play, which seems to be far away right now.


Power/Control of test string
9
I feel it would be fairly straightforward to adjust power level via reference tension for clients wishing to play this string, especially if one has an awareness of the player’s level and style of play.

Personally, I did not have to adjust my strokes much while hitting with HDMX. From the baseline, I was able to swing normally and produce deep balls that landed with good margin inside the opponent’s baseline. From around the service box, this was sufficiently crisp and controlled for volley rallies, put away volleys and overheads. In doubles, I could generate sufficient control and spin on cross court strokes from outside the sideline to confidently hit the ball over the net and into the opposing alley ten feet from the net. My serves had good pop and pace, I could place serves with relative accuracy.


Feel (Comfortable? Stiff? Mushy? Muted? Crisp? etc.,)
9
Nearly perfect (for me) – I had confidence from the firm, controlled and crisp response and it was quite comfortable. I did not feel much harshness on off-center hits. I am not sure how much of this can be attributed to the 1.35mm reading


Spin
7
Spin production is not an issue for me so, compared to other smooth (round) strings in full bed, I was able to produce comparable amounts of spin. Comparing it to shaped strings like Solinco Hyper G, TO Firewire or Weiss-Cannon UC would not be fair. Given the gauge of string (1.35mm as measured pre-install) I can see the 1.25mm offering a bit more.

Durability
8
I am not a string breaker in general and usually only on a shanked overhead near the top while using 1.30mm (natural gut or Tec X1BP or Prince SGD).


The fact that my string sample measured 1.35mm before install may be contributing to its longevity.

The test string did not develop abrasions after 30 minutes of warm up hitting and four hours of doubles on hard courts in the first session. Since then, this “hybrid 3D” string has made it through an hour against a ball machine, one hour of singles and almost another six hours of doubles on hard courts and seems to be wearing well. For me, this string has shown exceptional durability compared to a traditional multi-filament or hybrid of co-poly and synthetic gut and seems to justify its price point.

Playability Duration
9
HDMX in full bed has maintained its playability over the course of the test and has not give reason to doubt that it will be playable until a snap.

As indicated above, I liked this string a lot.


Tension findings (if you installed this string again, would you select the same tension? Explain answer.)
I am happy with the selected tension and associated playability duration. However, I would not go any lower next time in my racquet with that string gauge.

List any additional thoughts (optional)
The combination of comfort, control and durability makes playing with HDMX better for one’s pocket book than using X1 Bi-phase or natural gut in a hybrid with co-poly where the latter may not have as long a playable duration.

This string is only offered in 1.25/1.30/1.35mm and I am committed to testing the 1.25mm/17g at some point because I think this is a super string.




Tecnfibre Overgrip Playtest
Please briefly list your likes and dislikes of the Tecnifibre overgrip you were sent.
I received a single pack of
Tecnifibre Pro Contact overgrip in white.

I prefer this overgrip compared to the latest edition of Tourna Tac and Wilson Pro. However, there is an element of “slippery when wet” to it so I would use this in cooler weather rather than in the humidity of summer when my palms get damp (even with a wristband).

Would you consider using it regularly?
Absolutely a convert with one question – why not make these a bit longer? I came up short on an L5 with this as a second overgrip

ahhhh, one last thing i forgot to include. ive noticed some posts on here about the sound. the string definitely makes a solid WHOP sound on well-struck forehands and serves ... very similar to the sound Velocity makes. I like it, personally.

G.O.A.T.
scotus' review of Tecnifibre HDMX 16 gauge


Tension(s) used for playtest

52 lbs, machine-prestretched 20%

Regular string set up & tension
Ashaway Kevlar 18 Mains 72 lbs / Ashaway Monogut ZX 17 Crosses 46 lbs; Ashaway Kevlar 17 Mains 70 lbs / Ashaway Monogut ZX 17 Crosses 46 lbs; Tecnifibre HDX Tour 52 lbs

Racquet used for test
Dunlop Revelation Pro Tour Superlong (28 inches long), a racquet from the 90's but still the best for me.

Power/Control of test string:
Plenty of power, more powerful than HDX Tour in my opinion since I feel the need to go up in tension next time by 2-3 lbs for optimal control. Great for all court play. Excellent feel and control for volleys, drop shots and lobs. One shot I often have trouble hitting with the Kev/ZX setup is the defensive lob, which tends to fall too short. No problem with the HDMX in that department.

Feel (Stiff? Mushy? Muted? Crisp? Comfortable?)
It is an incredibly comfortable string. If you're used to polys, you might say it feels like a very soft poly. If you're used to multis or synthetic gut, you might say it feels like a very crisp multi or synthetic gut. To me it feels crisp and comfortable, somewhat muted, very responsive, and neither stiff nor mushy. It is perfect for someone who wants the comfort of gut/multis but wants some of the spin/control of a poly string.

Spin
HDMX has the spin potential of an average poly. I think the spin is slightly better than HDX Tour. When I first strung it up, I played in a doubles tournament. I was pleasantly surprised by the amount of side spin I was getting with it, especially when I hooked a topspin forehand and pulled the opponent out wide; the opponent noticed it, too, when he shanked a few of those and complained to his partner about the spin of my shots.

I was definitely getting more topspin, sidespin and backspin than with the Kev/ZX setup. However, I had reservations about hitting through the ball for more penetration and putaways, because I sailed some of them long. With the Kev/ZX, I had it dialed up to the right tension, so that I could just drive it, hit through the ball with plow, but with HDMX, I had to brush, slice and dice to play well with it. I think a few more pounds in tension might be the answer.

Durability
Excellent! I played 20 hours with this string, and it's still holding up well.

Playability Duration
Excellent, just like the HDX Tour! I am pretty sure it would play well until I break it. Maintains tension almost like natural gut.

Tension Recommendations (would you string it differently next time - why)
Just by feel, I kind of guessed this would be a livelier string than HDX Tour, but I kept it at same tension and applied 20% prestretch to compensate for it, but in hindsight, I should have gone up 2-3 lbs in tension. It's not that it loses tension; in fact, it is great at keeping tension, but it is a more powerful, lively string than HDX Tour, so I would need to go up a bit in tension.

List any additional thoughts (optional)
I think I'd be quite tempted to try a hybrid of HDMX and HDX Tour. Which should go in the mains and crosses, I am not entirely sure, but it definitely piques my interest.

Tecnifibre HDMX 16

A big thank you to Tennis Warehouse for the opportunity to play test this string.

Tension used for playtest: 58 lbs.

Regular string set up & tension: Volkl Cyclone at 57 lbs.

Racquet used for test: Wilson RF97

Power/Control of test string: Easy power. Good control. If you missed, it had nothing to do with the string.

Feel Very good in all areas- ground strokes, volleys and serves. I could hit drop volleys easily.

Spin I really liked how you can easily flatten out your shots. You can really drive the ball through the court. At the same time, you can hit spin if you want.

Durability Too soon to tell although was fine after 6 sets of doubles.

Playability Duration Too soon to tell although was fine after 6 sets of doubles.

Tension Recommendations 58 in my RF97 was ideal.

List any additional thoughts This string hits a much more linear ball than Cyclone obviously. I was playing better with this string-- hitting confidently and dictating points. You can really flatten your shots. At the same time, this is a comfortable string which is very nice in a fairly stiff frame. I may switch to it.

Overgrip: Very good.
 
  • Tension(s) used for playtest: 55
  • Regular string set up & tension : Hyper G or T1 Firewire at around 53 pounds
  • Racquet used for test: Babolat Pure Aero 2016
  • Power/Control of test string: For it being a multi, it was relatively lower powered but it wasn't a bad thing. The multi had excellent control, which I feel was the idea of the construction of it. I could feel the ball as it hit my strings, and was very point-and-shoot for me. Power is 6/10, control is 8/10.
  • Feel (Stiff? Mushy? Muted? Crisp? Comfortable?): The string was super crisp and comfortable. Usually crisp mutlis have a very lively feel, which then gets erratic, but this was not the case. Possibly due to the construction, it was meant as a more controlled, less lively, multi. Considering that, it was very comfortable and had no elbow issues whatsoever.
  • Spin: Spin was not the highlight of the string, but yet, spin is never a highlight of most multis. The string didn't snap back as much as I would have liked, but at the same time I did not expect it to do so. I really had to crank up the swing speed on my serve and strokes for added spin.
  • Durability: I broke it at around the 7 hour mark, and I usually break polys around 10-15 hours mark. Multis are not made to last, so nothing out of the ordinary here
  • Playability Duration: The playability was pretty constant throughout the 7-ish hours. There was no real drastic dropoff in playability. I feel like I broke it before it had a chance to die
  • Tension Recommendations (would you string it differently next time - why): I would love to have gone super high to see how the string would react. I would love to have gone at 60 or 62 to see if it is still comfortable and if I had the point-and-shoot control
  • List any additional thoughts (optional): No real complaints, as honestly the multi did not feel anything out of the ordinary. It was a more controlled multi, and not as lively. I would have liked for the green to be a bit brighter though, it was a bit dull :-D
EXTRA CREDIT - overgrip question
  1. Please briefly list your likes and dislikes of the Tecnifibre overgrip you were sent.: The grip was not meant as a tourna style grip, and is meant to be a bit more tacky than absorbent. Personally, I liked it because I do not sweat as much in my hands, but if you like an absorbent grip, stay away from this one.
  2. Would you consider using it regularly? No, I felt like it felt too plastic-ish for my liking. I find that is the trend for most black overgrips though.

Tensions used for playtest: Tecnifibre HDMX 16 on Cross only at 53 lbs. (Used Volkl, Cyclone 15L Main, 52 lbs.)

Regular string set up & tension: I have been using Ashaway Kevlar 16 main, 55 lbs and Prince Tour XC 15L cross, 53 lbs setup for over a year. Now, I am experimenting with 16/15L shaped poly main, ~53 lbs and 17/16 round poly cross, ~51 lbs. I have been using mostly Kirschbaum, Volkl, Weiss Cannon, and Tier One brand strings.
For the playtest review, I would like to make a comparisons based on one of my recent preferred string setup; Cyclone 15L main, 52 lbs and Kirschbaum Pro Line Evolution cross, 50 lbs.

Racquet used for test: Head Liquidmetal Mid (93 in2) 18 x 20, customized at 18.7 Oz (530 g).

Power/Control: Playtest setup provided much more accelerated balls using the continental grip; however, trying to bring the powerful shots just inside the baseline using the continental grip was a challenge.

Feel: Playtest setup provided more crisp and comfortable feel during the ball impacts at the net or the baseline.

Spin: Although the spin was there as needed, I couldn’t generate much spin as my preferred string setup.

Durability: HDMX lacks durability because the HDMX multifilament infused material, polyurethane, is softer when it’s compared with poly string. However, using the string savers or string lubricant may extend durability of HDMX.

Playability Duration: Playtest setup provided better playability even though there are many deep notching all over the HDMX cross string with some fraying.
I am not sure if this is a result of my main string staying so fresh. With my preferred string setup, 6 hours of hard hitting would have notched main string heavily and not the cross string.

Tension Recommendations: Playtest setup as a cross string at 53 lbs was very comfortable for me. I may vary the tension within +/- 2 lbs based on the main string chosen.

List any additional thoughts: I use the heavy racquets and I never had any problems using any poly or Kevlar strings over 11 years. I enjoy using the mid-size control oriented racquets with 18 x 20 string patterns with the thicker gauge strings so that I can spend more time playing tennis, rather than stringing. When it comes to the string breakage, my main string almost always breaks first due to the heavy notching throughout the string. However, my cross string seldom notches and elongates to somewhat elliptical shapes by the time when the main string breaks.
Stringing the Tecnifibre HDMX 16 was easy compared to poly strings. When I got done with stringing, I couldn’t move my Cyclone main sideways with my fingers, and was only able to move HDMX cross strings along main direction. My first impression was that my string setup wouldn’t work well because there was no snapback. However, to my surprise, it performed very well. After 6 hours accumulation of hard hitting tennis, the Cyclone main looks pretty fresh with almost no notching; whereas, the HDMX cross got notched all over and with some fraying. Compared to my Cyclone main and Kirschbaum Pro Line Evolution cross setup, HDMX cross setup provided much better feel, power, and playability with similar but bit less control capabilities. For me, the durability of HDMX is the biggest drawback.
I am going to playtest until the string breaks, and planning on a new playtest setup with Kirschbaum Max Power 16 main, 48 lbs and HDMX 16 cross, 53 lbs. Hopefully, this setup will provide an even better performance.
And lastly, special thank you to @TW Staff for the HDMX playtest opportunity and a very positive experience.

Likes and dislikes of the Tecnifibre overgrip: I really liked the feel and the tackiness of the Tecnifibre overgrip when my racquet hand was fairly dry. The overgrip performed well and the effectiveness is still present after 6 hours accumulation of hard hitting tennis at the outdoor tennis facilities.
I didn’t like how the overgrip effectiveness disappeared completely after it got wet during the play. I had to wipe the overgrip dry with a dry towel, and let it dry over 10 minutes before I could reuse it with a confidence. In addition, it would be more desirable if the overgrip is little longer in length.
My present overgrip is Yonex Supergrap, and I prefer the feel of the Tecnifibre overgrip.

Would I consider using it regularly? Yes, most definitely…

I enjoy using the mid-size control oriented racquets with 18 x 20 string patterns with the thicker gauge strings so that I can spend more time playing tennis, rather than stringing. When it comes to the string breakage, my main string almost always breaks first due to the heavy notching throughout the string. However, my cross string seldom notches and elongates to somewhat elliptical shapes by the time when the main string breaks.
Stringing the Tecnifibre HDMX 16 was easy compared to poly strings. When I got done with stringing, I couldn’t move my Cyclone main sideways with my fingers, and was only able to move HDMX cross strings along main direction. My first impression was that my string setup wouldn’t work well because there was no snapback. However, to my surprise, it performed very well. After 6 hours accumulation of hard hitting tennis, the Cyclone main looks pretty fresh with almost no notching; whereas, the HDMX cross got notched all over and with some fraying. Compared to my Cyclone main and Kirschbaum Pro Line Evolution cross setup, HDMX cross setup provided much better feel, power, and playability with similar but bit less control capabilities. For me, the durability of HDMX is the biggest drawback.
I am going to playtest until the string breaks, and planning on a new playtest setup with Kirschbaum Max Power 16 main, 48 lbs and HDMX 16 cross, 53 lbs. Hopefully, this setup will provide an even better performance.
And lastly, special thank you to @TW Staff for the HDMX playtest opportunity and a very positive experience.

Likes and dislikes of the Tecnifibre overgrip: I really liked the feel and the tackiness of the Tecnifibre overgrip when my racquet hand was fairly dry. The overgrip performed well and the effectiveness is still present after 6 hours accumulation of hard hitting tennis at the outdoor tennis facilities.
I didn’t like how the overgrip effectiveness disappeared completely after it got wet during the play. I had to wipe the overgrip dry with a dry towel, and let it dry over 10 minutes before I could reuse it with a confidence. In addition, it would be more desirable if the overgrip is little longer in length.
My present overgrip is Yonex Supergrap, and I prefer the feel of the Tecnifibre overgrip.

Would I consider using it regularly? Yes, most definitely…

18.7 oz frame?? wow!!

EXTRA CREDIT - overgrip question
  1. Please briefly list your likes and dislikes of the Tecnifibre overgrip you were sent.
  2. Would you consider using it regularly?

We will get rid of "applied" posts, but feel free to talk about strings and Tecnifibre!
Hi TW and All:

Is this the final product we tested? I tested a string that came in a demo packaging?


Thanks... loved the string.

Going out on a limb:
b) HDMX = High Density Multifilament X____?? All a guess and I don't know about the X - may be bec of the twist within the structure OR that twist in the cross section graphic is more marketing? However, "HDMX" does not roll off the tongue.

b) so, MAYBE the marketing department tried to show their creativity: Floro from Fluoro from the fluoresecent green/yellow color. "Floro" is easier to speak.

@Tecnifibre Official - any insight?

That is a wonderful answer and I am guessing you have most of it is correct. If you goggle "Floro" you do not get a color... :). Your explanation is great. I think the string is great. I am not a super big fan of the color since I am an older person and a "guy"... I bet it matches many of the current frames being sold.

I am loving the fact that they are making these poly /multi ..or multi /poly hybrids.

The price point is not that bad for a Tecnifibre multi... since X-1 is almost $20.00.

Thanks for your insights!

Tension used for playtest---55 lbs.

Regular string set up and tension---Head Rip Control 17, at 57 lbs.

Racquet used for test---Prince Graphite Classic 100.

Power/Control of test string---like others have said, it's more powerful than your usual poly. But I'm not used to a 16 gauge string, so it was alittle tough to control.

Feel---pretty crisp and somewhat comfortable. I'm glad I didn't string it any lower.

Spin---so-so. I'm so used to 17 gauge strings to create spin. I'd gladly try this stuff in a 17 gauge anyday.

Durability---looks like a very tough string so far. I'm a 4.5, but not a string-breaker. Hasn't notched yet.

Playability duration---had to put more topspin on it to produce results.

Tension recommendations---when I try this string again (hopefully in a 17 gauge), I'd stay at 55 lbs. (When I try a full poly string, it's at 52 lbs.)

Additional thoughts---I love decent 17 gauge multis, like Rip Control and Intellitour---I don't like full poly or any hybrid setup so far. I can't wait to try HDMX in a thinner gauge. It would probably kick ***.
The next step in the string industry is, obviously, to create a decent poly/multi hybrid in one string, and I think the smart folks at Tecnifibre have done that. Bravo.

Tecnifibre overgrip---I usually use Tourna Mega-Tac. This TF Pro Contact is surprisingly very similar. I'd buy a 12-pack of this stuff anyday. 10 thumbs up!!

(Thank you, TW, for the opportunity of this playtest!)
Great review! I switched to the PCG 100 this fall, and absolutely love it! I normally play with a full bed of Prince Premier Control, but the string movement with that multi and the 16x18 pattern is driving me nuts. So I was thinking of trying this HDMX to help with that. Did you ever try it out in 17g? And how did the string perform for you as far as not moving when you tested it. Also, any other string recommendations for this great racquet would be much appreciated if you have the time. Thank you so much.

P.S. I know a company in Europe that still has new ones in stock if you need more. But there are only size 1 and 4 left.
