In praise of Kevlar/ZX hybrid!!!

Sorry My bad. Initially i felt like it was reg. Kev but its the same Kev+. I played with fully prestretched kev+/ZX @60/45 this time for 1 hour and still like it a lot without any major differences to 55/45, may be power was just tad less. Hopefully this time it will last longer than last time (14 hours). Anyways i just ordered 2 half sets of 16g regular Kevlar and 200' reel of ZX, and will try @60/45 once the current one breaks, i am sure it will last much longer.
As I recently joined the Prince 93P club, I await your review on 93P wtih high differential Kev/ZX set-up.

Quick update. I managed to buy 2 x Crossfire II pack cheaply from a boot sale here, still with the old packaging (blue background instead of the current black background). I took the 16g kevlar out and pre-stretched it by 2 inches+, pre-stretch the ZX string from my Crossfire ZX pack by around 50-60cm. Dropped it off to another stringer with a Wilson Baiardo and asked for 90/35 for my APD2013. The numbers raised a few eyebrows with people in the shop but he took the job. Let's hope he's not the type that promises one thing but delivers what he deems is safe.

Is there any easy way to check for tension accuracy once you get the racquet back from stringer?

Assuming he doesnt break the zx i would measure the racquet. If he did the specified tensions you should find it a bit shorter than the 27” assuming its normal length and not an extended frame.

Good for you trying the whole deal. Hope you dig it

Good suggestion. Will measure the racquet length when I get it back. I never measured the lengths of my racquets before, let's hope Babolat QC doesn't throw a spanner in the works...

Haha yeah as a rec/hack player tinkling with stuff is part of the enjoyment.

Got my APD2013 (tensioned at 90/35) back. Measured racquet length, and it measured 1/8 inch shorter.

Measured my O3 Tour Mid (kev+/zx tensioned at 75/40) and it is now 27" on the dot.

Played about 3 hours singles over 2 days with the APD. I like this set-up on the APD more! I play the racquet stock and did not add lead tape to compensate for swing weight loss.

Perhaps it is the combination of free power from the tweener stick with low-powered KV/ZX set-up, but I can feel the ball bite and controlled power/spin much better than the O3 Tour Mid. Perhaps also due to the 16g regular Kevlar (as opposed to the 17G Kevlar+ in the O3 Mid), or the larger tension difference for the APD. Not sure which it is, but the racquet plays very well and with good comfort/feedback on ground strokes and services (both flat and top-spin). Slices on both wings felt to have more spin too compared to the APD's previous set-up of Sensation/YPTP at 54/50.

I can say I'm sold on this poly-less set-up now for my racquets. I don't break string easily so this Kv/ZX should hopefully last until it breaks while keeping playability, which is why I wanted tried this set-up in the first place. Thanks @travlerajm and @Shroud and everyone else in this thread for your input!

If only the pre-stretch routine is easier.

How is power/spin compared to a 40-45 lb poly like cyclone?
I had my Kev+/ZX pack on the racket at 60/35 for months now and sometimes I do wish for more power (maybe it's the stick).
I can always cut it out but I'm out of kev/zx packs and would hate to cut out decent strings.

Kevlar is lighter than poly so if you havent you may want to add some lead to make up for the loss in swing weight
 
Its been 6 hours with Kev+/ZX @60/45 and its holding up really well. I don't remember when i started seeing the notching on Kevlar+ last time but it still looks good so far. Playability has been consistent with decent power/Good comfort, control and spin even in low temperatures (48 F). So far it looks like i may get more than 14 hours this time. Will post the results but anyways i have 2 half sets of regular Kev 16g and mini ZX reel to try next time in my Angell TC95. I have been wanting to try this hybrid but some how scared by seeing Kevlar :). After trying recently i feel its the most comfortable setup ever for me including Gut/poly or Gut/Multi setups i have tried (Never tried full gut though). It may be little muted but very comfortable setup and i will definitely have this setup in one of my racquets. I may not try bigger differentials like 90/40 or 70/40 but 60/45 seems fine to me. Big Thanks to all the contributors to this thread and make us believe that this setup really works.

I have a TC100 that I have been using with Gut 15L/Poly at 62/46 - I have really liked this set up and it lasts forever. I have used Kev/ZX a lot in the past in various rackets and finally tried it yesterday at 60-45 in the TC100 - definitely felt more control (that ability to really swing out and the ball seems at times to magically drop in) with a bit less power and more spin. Need to give it more time but if it does not bother my shoulder I would probably have one frame strung with Kev/ZX and one with Gut/Poly when I want more free power.

I have one racquet (TC95) with gut/poly(legend/max power) and the other one with kev/zx and I am preferring kev/zx in the matches for the control. And I may be wrong but I feel I am able to control the trajectory better with kev/zx and band hand slice is deadly as well. Where as I get easy depth with gut/poly but in tight situation some times balls fly on me. And trajectory would be little higher with gut/poly..of course it could be my technique. But control is insane with kev/zx without the loss of much power. We can really swing out and put great rpms on the ball. My returns (blocks or drives) against big servers are more consistent now with kev/zx...both are great setups overall for different situations...

Well said and I agree with everything you said, in a match where one might want more control then Kev/ZX, in a match where one needs more easy power and depth then Gut/Poly. In some frames Kev/Zx has bothered my surgically repaired shoulder in other it has not, have to wait and see how in does with my TC100 70RA - gut/Poly was no problem.
 
After the match today, I noticed just couple of deep cuts on the kev+ in the middle of the sweet spot and rest looks brand new, after 9+ hours/. So I may not get more than 15 hours this time as well. One more thing I have been noticing is, ZX moves little bit and just needs some adjustment but not too bad. If I move zx with hand, then I need to manually move it back. Is this normal? Kev+ always comes back to its place...seems like Regular kev 16/zx 17 is the only option for durability..my gut/poly hybrid has 20+ hours on it but it will easily come for more than 10 hours just that gut started moving little but in the middle. Saying this just to mention that I am not a string breaker. Anyways I am still happy but just missing the durability with kev+/zx. And hoping ref kev/zx makes last’s longer and matches the comfort...

Yeah makes sense. When you move ZX string out of position, it needs to overcome your higher tensioned Kev+ to return to its position. Vice versa for Kev+.

Played a singles club league match last night with my APD2013 strung with Kev/ZX @ 90/35. Lost the match at 7-6 (7-4), 4-6, 6-10 (3rd set is tie-break to 10 only). For some reason my mind went wandering in 2nd set and I was down 0-4 at one point. Pulled myself back to 4-5 but double-faulted at a couple of crucial points to lose my service game and the set. Opponent didn't have good services but could send most of my ground strokes back to me. He had a much more consistent ground stroke game than me.

I hit a number of forehand shots wide when I tried to switch direction, and volley unforced errors were about 50% by gut feel, which was extraordinarily high. Even my trusted inside-out forehands were abyssmal, and couldn't put away the 2 or 3 short balls that were gifted to me. I found myself longing for the 93P's control but stubborness won out, since my first serves were getting better as the match progressed. I stuck with the APD and lost the match in the end due to the number of UEs I had and mental lapse. Positive takeaway from this match is that even with the APD in hand, I came to the net more often when the opportunites presented themselves, instead of rooting on baseline. Sure there were baseline rallies, but recognising short balls and go for DTL approach shots, and move in when opponent struggled to return, those were my coach's teachings and I think I did that better last night than a few months ago.

No issues with comfort, for those who are reading this post and wondering about that the high tension differential set-up in stiff frame like the APD. I was hitting out fully on some of the baseline rallies and have no discomforts in my arm.

Broken record here: Does anyone has the SM data after strung main strings b4 crosses were installed?

For a non-stringbreaker, CrossFire ZX (Kevlar+/ZX) on an open pattern (110 sq. in. 16x18) showed to be a good buy. Without pre-stretch, the tension would continue to drop. ZX cross can be retensioned, I pulled it twice. Now broken I had it with a soft poly. The string bed remains to be low power and consistent. I might try it with SG cross next time just to experiment.

Cool report. And kudos for sticking with the new setup.

Its hard to tell if the issues were from the new racquet or the string bed or just some lapses. Maybe all three?

And thanks for speaking to the comfort. I agree that it only looks bad on paper but in reality its not harsh like it sounds.

There are some posters that see bab and kevlar and 90lbs and wig without understanding what is going on.

Ok I can now say definitively that prestretching ZX does absolutely lower the reference tension that it can be installed at without breaking. The thinner gauge and the black color are the most susceptible!

Initially was doing a 6" prestretch of a half set, and that would never survive 58 lbs, but 53-54 was fine.

Fast forward 6 months, upped the prestretch to 12" and now 53 has failed multiple times !

I used to try and blame the grommets for these problems but now I understand that the string is weakened by the prestretch. My advice is that for every 1" you pull out of a half set you need to reduce the top limit reference tension by a 1lb.

I still whole heartedly endorse prestretching the ZX as there will not be any issues of durability after a successful install, but you've got to adjust the pull tension while stringing!

I feel it’s more racquet than string bed. I think this string bed shines more with little heavier and flexible racquets. My racquet is 350 gms static weight and arnd 340 sw..I am able to generate very heavy ball with tons of spin with great directional control...this string bed should feel better in 93p than APD...I may be wrong..just my 2 cents...

The recycled ZX are breaking towards the end (@53) and the first install ZX don't even make the upper hoop -side grommet slot before breaking. This is with a pros pro drop weight (both SM and RT are supporting my tensions)

Again, I will report my advice that for every 1" inch prestretch on ZX you need to cap your reference tension by 1 lb. (A linear drop weight pull is very accurate)

I wish I could show every over 55 yr old tennis player how these rackets play. Control, enough spin if you have the technique, decent flat shot if you have your own power and arm comfort like a multi without launching the ball to the moon. Get all that for a very long time - playability/durability.

I did notice that ball depth was actually fantastic - I don't remember any balls sailing long, or if there were, very very few of them. So the combination of this stringbed + APD's power worked very well in this regard in my opinion.

I'm gonna offer up another possibility in addition to my technique and mental lapse - 16/19 open string pattern. My other racquets are mostly 18x20 (in 93/95/98 sq in heads) or 16x20 (95 sq in head) with higher string density. The APD2013 is my only 16/19 100 sq in racquet. It was probably unwise to switch to this racquet for a match play in hindsight, but I wanted to see how this combo holds up when I put my mind in match play instead of the characteristics of the stringbed. As I said, my flat/slice serves got better as match progressed, so there's no issue with the spin/control of the string bed in that regard.

@Tennis Passionate haha that's why I wanted to see your review of kev/zx in 93P first :p

Likely going to come over to the "no manual prestretch of ZX but instead string slow and at max tension" camp. 59 lbs with about a 10 sec pull resulted in a stringbed that was silky smooth + sweet dwell time!!

Power is bumped up a little, but no lesser control in my initial hitting.

It appears that merely stretching the ZX a lot still keeps it in a more gut-like condition, but that deforming ZX (through a manual prestretch) transforms it into basically "poly-lite" in terms of feel.

sounds right but another reason to do the manual prestretch is to lesson tension loss. Be interesting to see how long it plays well. FWIW I do manual, machine (20%) and do slow long pulls with the machine pulling while I thread the next cross....maybe 5 min :)

Smart.

I bought another stringer to string it up and hold the string in with 4 starting clamps. So it would be ready to string when i needed it. Lol. Never did it though and after 2 years of the box being unopened i gave the stringer to my tennis bum buddy who was living in his car. Pretty sure he sold that to feed his vintage racquet habit.
 
I played with reg Kevlar 16/Zx @60/45 fully prestretched. Not much change in my feed back. It’s still great and I still love it...this may be little crispier, slightly less powerful, control and comfort are great, compared to kev+/zx...overall I really liked it and expecting it to last longer...it’s very windy and couldn’t play longer. But will post more updates after couple more sessions...but one thing is, this is little less muted compared to kev+, which is good...

just bought some zx myself. Its not usable in my normal sticks but I am trying a super light one and will need extra pop. ANd it was on special.
 
7+ hours on reg Kev 16/ZX 17 @60/45 for 7 hours and i only have positive things to say. After couple of sessions it started feeling like butter. I feel like this combo was made just for me :). I have been looking for a string with good control, comfortable, spin potential, decent power level string and i finally found the answer (RS Lyon is another string which i like). So far i don't see any major notching/damage on the mains. I will be more than happy if it can give me around 25 hours of consistent playability. kev+/ZX hybrid was great as well but i only got 14 and 15 hours in 2 attempts being a Non String Breaker. The thing that i can just swing out even during tense moments increased my confidence and this combo is really helping me in the matches. I will have at least 1 or 2 racquets strung with this combo. btw i am a decent 5.0 USTA player with Eastern 1HBH and E/SW forehand. Thing combo really helped my top spin BH and slice as well. I can just rip without worrying about ball going long. Believe me this combo works and kudos to Shroud, Travlerajm etc for giving us the confidence to even try this combo. Really happy and appreciate all the contributors.

Trav invented it so kudos go to him. Thanks for updating us and do try a bigger differential sometime. Hopefully people will try it themselves and see just how buttery things can be even with kevlar...

Just had 1 hour+ match play last night with my APD2013 with 16g regular kev (from Crossfire 2 pack) and 17g ZX Pro, strung at 90/35 (stringer uses Wilson Baiardo). Before the game I have put 2g lead tape at 12 and about 5g of Blutack inside the buttcap, while changing the replacement grip and overgrip. Didn't have time to measure the racquet specs, so I just went by feel / shadow swing.

This time round I tried to aim for bigger targets (e.g. aim for within bottom half of NML and within >1m of side lines) and did less risky shots, knowing open string pattern is not meant for thin DTL shots. And it paid off. Beat my opponent 6-2, 6-2. Honestly I like the spin (opponent commented I was hitting with way more spin) and comfort of the stirngbed, and it comes with longevity of playability. This is gonna stay in my APD now.

Awesome report man. Its such a great feeling when the opponent comments on the increased spin! And comfort is nice too! Kudos for not wussing out on the huge differential and not stopping at 15lbs like many who report.

Had a talk with a Russian D1 female player yesterday about her strings. I had strung a couple of her rackets with 16g Ash Kev x 17g Zyex this summer but I hadn't seen her in a while to talk till yesterday. I asked her how she liked playing with the college's Tour Bite. She told me it breaks too quickly and doesn't give her the control that Ash Kev x Zyex does. I told her give me some rackets. I strung 3 of her rackets up with Ash Kev (winch prestretched) x prestretched Zyex. She had a 4th racket strung with Ash Kev x Zyex she had been saving. She was elated to have 4 rackets strung with Ash Kev x Zyex. I told her to hit with them 1.5-2hrs before matches to break in the string bed and let me know when she needs a racket strung. The coaches and tennis center manager have no idea what Ash Kev or Zyex is or how to string it.

Yes, after stringing couple of my racquets with kev/ZX, its tough to play with any other string since the level of control and comfort with kev/zx is amazing. Even a low powered string like RS Lyon seems powerful to me now. I am a big hitter and with Kev/ZX my game went to next level since this combo allows me to swing 100% at any point of time during the match without holding back. With other string i may be trying to control the swing to keep it in and i can't get my racquets strung every 8-10 hours with polys for best performance. btw, i give this combo its share for helping me to win local league called Ultimate Tennis at 5.5. level (May be USTA 4.5-5.0). With Regular Kev 16/ZX 17, its currently at 16 hours and there are 2 spots right in the middle that may break any time and rest looks very good. So i may not be getting much more durability out of reg kev compared to kev+ (15 hours). Seems like ZX is really cutting through Kev. In general i hardly break strings even the NG survives for 30+ hours and multi close to 20 hours.

How tight did you string her frames?

What tension did you string her frames. This will be a good test.
