In praise of Kevlar/ZX hybrid!!!

Anyone thinking they are healing their arm by playing with Kevlar is confused. The high differential with a soft cross string may make it tolerable but using Kevlar to heal is bad thinking. Using the stiffest string on the planet is not arm curing. Low tension gut combinations, multi or synthetic gut are more in the realm of playing with set ups that could assist in arm pain provided the frame is fairly flexible.
I have met up with TypeRx in my travels and hit against him. His hitting style is very Nadal-like - he hits with more average topspin rpm on his shots than anyone I’ve hit with. He uses massive heavy spin as his primary weapon to make it difficult for his opponent to control the launch angle. Given his preferred playing style coupled with his need for comfort and durability, it’s not surprising what his current string choice is. I think a full bed of gut or soft multi would be counter to his spin-based game, and he’d break those in less than an hour anyway.

I would hope anyone (myself included) knows that no string heals an arm/tendon injury. That is ludicrous. In my example, like I wrote, my elbow healed while I was using Kev/ZXP in Volkl VS8 rackets. I do believe that using that combo allowed me to continue playing as my body healed itself, which took some time. Whereas I would feel the need to ice immediately after playing with fullbed poly or even poly/syn gut hybrid, I did not experience acute pain with the Kev/ZXP setup.

LOL -- first and last time anyone will ever use me and Nadal in the same sentence.

I've tried (and wanted to love) gut/poly and have tried several different polys (Hawk, Revolve, Cream, Cyclone) and could not generate anywhere near the same amount of spin as with Kev/ZXP. The gut hybrid setups felt great though! I loved the touch and adapted to a more chip and charge routine when using gut/poly since my groundstrokes weren't quite as effective. On a tangent, I cut out a gut main and had enough to reuse as a cross with Cyclone. While I wouldn't do this regularly -- man, I got most of the lost spin back and maintained the crisp feel on touch shots and volleys. It was great but the setup broke very quickly.

I've tried several multis and really don't see the point. They fray super quick, have too much inherent power for me, and are more expensive than the polys I like or Kev/ZXP. Oh, and they don't have the bite I like. I suppose they are very comfy though.
 
I too found the RF97A too harsh, especially on off-center hits, with poly or Kev/ZXP compared to my Bab PD+ and definitely my Volkl VS8 (both with Kev/ZXP).

I used Kev/ZXP nearly exclusively through a bout of moderate-severe GE and healed while playing with the VS8 and Kev/ZXP. I now play 5-6 days a week with 2-4.5 hours per day played and thankfully am never slowed down by arm pain, although I am always concerned/aware it may recur.

The observation that you felt pain several days after playing is rather odd and I certainly don’t discount your experience. But, IIRC, you were experiencing elbow pain with just about every string/racket setup (outside of an old POG or similar with syn gut?) during that time period, right?

I think what we might find here should be no surprise, and that is that there is no panacea or perfect string setup for everyone. We each have our own preferences, sensitivities, biases, rackets, and play styles. Gotta experiment if you are up for it.

As a semi-aside, I am playtesting a Wilson Clash Tour right now and it is strung with a multi at 55lbs. Serves are easily 5-10 mph+ and I can hit with more spin, but I am having trouble controlling things when under pressure or really swinging out. It is a launcher. But the racket is like butter so I might buy one and try with poly (I am not completely afraid of a full bed of soft poly any more) or with Kev/ZXP at 75/45 like I do now.

I never thought the RF97A felt harsh. It felt awesome, but in the end, it was a little too stiff for my elbow and a little too heavy for my shoulder at the end of a long 3 sets. I'm currently using a racquet that is much less stiff than the RF97A, but frankly, I'm afraid after the 1st experience with AshKev/ZX to try it again.

And your remembrance is correct, I was experiencing elbow pain with most set-ups, though a lot less with some than others, for sure. None gave me worse pain a few days after playing than the AshKev/ZX hybrid did.

I'm trying a hybrid right now of Tonic Gut main x Tecnifibre Multifeel crosses and it's soft and has more spin than I expected it would, but I've only got 95 minutes of play on it and the Multifeel crosses are heavily fraying in the sweet spot and look on the verge of breaking already, though the Gut mains still look perfect. Going to try Velocity crosses next, think they'll be more durable than MF, but I think I'll get less spin with Gut/Velocity than Gut/MF. In the end, I may ultimately end up going back to a Gut/Poly hybrid and just choosing a really soft poly for the crosses.

I'm sure I am wrong but I like Multifeel more than just about any other multi. I think the fraying is a feature, not a negative. Multis like NRG2 make me think of immobile older players swinging 120"+ headed rackets. Which I think is a good thing for those players. But I am not quite there yet.

I've played with half a dozen or so different multi strings and I got noticeably better spin from MF than any of the others. But it is not durable if you hit much spin, as I do. I thought it would be more durable as a cross with Gut, but not looking like it. I'll be very surprised if it lasts another half hour before breaking.
 
my 2 cents is that it couldnt hurt next time to spray it with some teflon spray off the stringer and everytime you start to play. And when it starts to notch put in some babalot electrocrosses. If thats 18g I get the dillema. I liked that the best but it shreds the fastest.
So.... I sprayed the strings with silicone spray. I went it to play a 9.0 mixed dubs match. That unraveled main in the upper hoop snapped on the third shot of the warm-up.

I was really hoping to see if the silicone spray could extend the life of the stringbed. Oh well.... I'll have to string up some more.

18g sort of defeats the main advantage of kevlar
 
If one is experiencing elbow problems the best thing to do is go softer strings and lower the tension quite a bit. This is the only place in the world you can hear about people with elbow problems thinking that the stiffest string made/Kevlar is helping their arm recover more so than playing with softer strings at lower tensions.

That quest is still a "work in progress" for me. You should see my file with notes on all the different string (& racquet) set-ups that I have tried in an attempt to find a compromise that is comfortable on my arm and yet has the performance I need for my game style. Frankly, I would love to be able to just play with a full bed of Natural Gut as far as the comfort aspect goes. While it doesn't have as much easy spin as I'd like, I can get *enough* to make it playable for my game style. The problem is that in a full bed, it just isn't durable for my game style with lots of heavy spin. I can't spend $28 on a set of strings that isn't going to last me at least 20+ hours, and Gut won't. So, I'm still searching. As previously mentioned, I'm trying a hybrid of Gut mains and Multifeel crosses right now and like it fairly well, but after less than 2 hours of play the MF crosses are already on the verge of breaking, and that's just not long enough for what they cost.

There are a number of inexpensive options that can get you playing after sometime off the court. Following injury I switched to a IG Radical Pro which is a more flexible frame. Used Isospeed Baseline, a softer poly, in the mains and Prince Synthetic Gut Duraflex in the crosses at 46/48 and then 48/50. Playing 5.0 level tennis so the performance was there after some adjustment. $3.50 a frame. Using Tourna mains now with Gosen Micro at 48/48 in the cold temps.
Kevlar for people experiencing pain is a bad idea regardless.

Right now I'm alternating play between my Prince Phantom Pro 100 and my Phantom Pro 100p, so not going to get much better in the comfortable racquet department. So far, any set-up with poly, whether full bed or hybrid, soft or stiff, causes some problems for my elbow, some more than others, but all cause some issues. I've played a few SynGut's that are *ok* (not great) for my game, but I break them in 3-4 hours, and while the strings themselves are cheap, it would get real tiring having to re-string my racquets every week. As I can see things right now, based on all my experiments, the best compromise of comfort, performance, and durability is probably going to be a Gut/Poly hybrid, but my guess is I'll still have to ice my elbow, though not nearly as much as with full bed of poly.
 
been using this high differential setup for more than a year with my Prince Tour ESP 16x 16 and liking it . The initial stock weigh was like 10.4 oz i think so I added weight to the buttcap and a bit on 3 & 9 for increase torsional stability aka twistweight.

I finally added about 5 grams to the 12 point on the hoop, since this stick is so powerful with its super open string pattern. The thinking was to gain control via spin.

Just wanted to report back and say that IT WORKED! Of course there were some mishits and I was late some, but OMG! Ive always used tons of spin—both top and slice— but the added weight at the top of the hoop allowed me torque away and the ball nose dove back onto the court.
I am running Prince Tour 98 ESP’s weighted up to 380 grams / 10 pts HL. Lots of lead at 3/9 and 12 with leather grip and BluTack in the handle with the Kev/ZX hybrid and loving it as well. I am running 16g on both strings to combat the string eating 16 x 16 pattern and have recently been experimenting with higher tension differentials as well. Latest was 70 lbs x 50 lbs and I am getting less main string displacement as the string bed wears with no noticeable fall off in performance.

Gotta love the way the ball dives toward the court with this combo.
 
Lower tension may be the answer.
I've tried multiple full poly and poly/sg set-ups in the mid to upper 30's, and anything with poly still affects my arm. Much less in the mid 30's than in the low 50's, but it's still there. Going any lower will compromise my ability to control the ball. I've tried Gut/poly with Gut in the 40's and poly in the 30's, and that doesn't stay controllable for very long. After 6-8 hours I need to cut out the poly crosses and re-string fresh poly to help bring back some control.

Interesting. I went to low tension (40 lsh or lower) because I had terrible golfer's elbow from poly at 50+ lbs. Kev mains at 40 lbs with Ashaway MonoGut ZX at 40 lbs gives me zero pain. I hit pretty hard maybe not as hard as some of the guys on this thread but I don't play patty cake tennis like most of the people at my club

So...Kevlar at low tensions may not be the arm killer it is feared to be
 
The only time in my life I encountered elbow pain coincided with the only time in my Life that I played with full poly strung in the conventional way for more than a week.

It took me 2 months to recover from that episode. The offending frame was 6.1 95 18x20 strung with unknown yellow poly at mid tension that was still in it when I bought it - liked the way it played but it destroyed my elbow within a few days of getting the racquet - the isolated severe elbow pain injury may or may not have been related to nerve damage from whiplash in my neck, but I’ll never know for sure. Anyway, I restrung it with kevlar/zx pro at 90/40 prestretched, which played similarly to the full poly but was much more comfy and a bit more spinny, and was able to continue playing (minus serves) while my elbow healed up.

I’ve been using Kevlar mains 99% of the time for the past 30 years.

I believe what makes poly so dangerous to elbows is that the crosses tend to dent or notch, so that it requires a large shock impulse to dislodge the mains from the dents in the crosses. Kevlar mains have braided soft surface so they don’t tend to dig a dent into the crosses, especially with the hard zx surface where there is no noticeable denting or notching in the crosses at all.

The stiffness of poly (lbs/in) is around 200-240 with some of the stiffer polys on the market. The stiffness of Kevlar (lbs/in) is around 750-760.
THE STIFFNESS OF PROBLEND WHICH IS KEVLAR and SYNTHETIC GUT is 981 (lbs/in)
Zx can bring that number down quite a bit but Kevlar is Kevlar.
This thinking that string stiffness has nothing to do with wear and tear on the arm is incorrect. Because someone hits with a set up for a period of time and it doesn’t hurt the arm initially does not mean that it is not doing damage.(consult a sports doctor). Poly, with its stiffness rating is not suggested for players with incorrect form that don’t generate enough racquet head speed to use it. Majority of injuries with poly are players stringing too tight or poly is unsuitable for their game. Poly and Kevlar are best strung below recommended tensions on frames.
Travlerajm playing with a Wilson 6.1 18x20 players frame strung at 55 with full poly would be a recipe for arm problems.

Been a while since I chimed in on this thread, although I do read it every day. I'm not saying that I know exactly why this combo at these tensions plays so soft, but it does. I've read countless attempts by people to explain why and countless attempts by people that haven't tried it to explain why not. I think the only plausible response is to say try it and please skip the kevlar+ (it will not provide an experience that so many others have enjoyed). Now I don't think this combo is for everyone, but I have strange ideas about tennis and equipment anyways (like: TE is most directly caused by grip pressure, dampeners do practically nothing but change the sound of the string bed and if you have decent strokes tennis is mostly about your off hand, footwork and high percentage point ending decision making).

There I've said my peace and I'll happily pass the mic to the next in line.
 
Problend's aramid string construction is a twist of fibers coated with some kind of plasticky stuff. Ash Kev is not like that at all. It is braided. I've tried whatever commercially available aramid or kevlar tennis strings that are currently available and they don't play like Ash Kev when paired with ZX. But....thanks to @Ultra 2 I have a half set of Polyfibre D'Aramid 16g, some ZX Pro and an unstrung 1-stripe POG 90 with fresh grommets:) I will give this twisted coated aramid another try for a side by side comparison.

Played with Kevlar/ Synthetic Gut and Kevlar/ Kevlar for two years playing college tennis. We were stringing in the mid 40’s to low 50’s. The numbers don’t lie about the stiffness of Kevlar. Also have experience with injuries that befell myself and several team mates.
Zx is absolutely worth praising if it can actually make Kevlar playable with any sort of comfort which I tend to doubt due to the number of people that have spoken up about this set up hurting their arm.

Dude, that is exactly what I'm talking about. No one is debating whether or not kevlar is stiff. This is a thread about Kevlar + Zx, not something else. Without reviewing every post, I have seen very few reports of injury from this setup with the tension differential we are referring to.

Out of curiosity, what kind of spin did you get with that tension set-up, and with it being very low poundage, were you still able to get decent control?

One he's referring to is me. I played with it at 60x40 in an RF97A, and it hurt the heck out of my elbow a day or so after playing with it, and for the next week. Now, one caveat: I did use the Ashaway Kevlar + (with PTFE filaments), I did not use the straight Ashaway Kevlar as the mains. I see you say do not use the Kevlar +. Why do you say that, and do you have some scientific reason to indicate that using the Ashaway 100% Kevlar will be softer than using the Kevlar +? I would love to give this set-up another try because I loved, loved, loved the way it played with my game. But frankly, after how bad it hurt my elbow with AshKev+/ZX, I'm extremely reluctant to try it again. Convince me why I should do so with Ashaway 100% Kevlar mains and expect a different result than previously? And I'm plenty willing to drop the tension way down if you think that is a big part of the equation. What people like Shroud and travelerajm have been selling for a long time is the idea that the big *tension differential* between mains and crosses is a big part of what makes it comfortable. But that was not the case for me, or at least not with AshKev + mains.
 
I personally could care less what string you play with. Standard kevlar, from Ashaway, played slightly softer and lasted much longer than the + version in my personal experience. Also, I would have to watch your mechanics to have any idea as what it was that was causing problems.

Here's an example from my personal experience. I talked one of the best players I know into trying this combo out. He traditionally uses the prepackaged gut/RPM combo. He experienced discomfort which caused me to pay close attention to his strokes. I noticed he had a white knuckle grip on most of his stokes and was even potentially gripping tighter than normal to compensate for the loss of power vs his preferred string setup. I contend that this not the string caused his problems.

Maybe I should add that I have played full poly at 60 lbs in a racquet for several years, with no arm discomfort what so ever.

That’s ridiculous, if he hadn’t of put the string in his frame he would have had no arm pain. Not to mention you talked the best player around into trying this. That is the problem with people pushing Kevlar now just like they did in the 90’s when people found out Agassi used it for a period of time. This is an interesting group that blames the problems that have always been associated with Kevlar on not pre-stretching enough, differentials not being high enough, mains aren’t tight enough and now the problem is that the guy played with Gut/poly prior to playing with Kevlar/Zx.
One of the guys here has talked a D1 girl into playing with the string and she is breaking it in a week. That means it sucks for durability as well.
I have some ocean front property in AR I am selling. Trust me, it’s the best.

I don't have any videos of me on youtube so you can't watch my mechanics. I play at a 5.0 league level, played competitive USTA as a junior and have basically the same strokes now. I have been told recently by a certified teaching pro at the club I play at that I have very good mechanics. I can tell you that usually the only stroke on which I experience elbow pain sometimes *during* a match is when I hit a very hard 1st serve, or a hard slice serve. I occasionally will feel some discomfort if I have a mishit while hitting my one-handed backhand, but mostly it's just on a hard 1st serve. I should also add that I have recently visited a sports physical therapist for some PF/Shin Splints related issues and I had him evaluate my elbow also. I told him I thought that it was not actually a tendon issue (Tennis or Golfers Elbow) but rather that it might be an issue with my elbow *joint* itself. After doing some tests on me, he agreed that it was more likely to be something going on with my elbow joint rather than actual tennis or golfers elbow.

Also, I have played with string set-ups that were much lower powered than the Kev/ZX, but that hurt my arm a lot less than the Kev/ZX did. I tried a Tonic Gut/SynGut hybrid in my Prince Classic Graphite MP, strung it at 60x56 and it felt tight as a drum, very low-powered and not a very comfortable or pleasing ball impact sensation, but my elbow didn't hurt after playing with it.

Given that you can play with full poly at 60 lbs. with no arm pain at all, I would contend that you are not necessarily a good, average test subject to evaluate the overall comfort of a Kev/ZX stringbed as it would relate to the arm comfort of the *average* tennis player, whether they play at a 3.0 level or a 5.0 level.
 
Moral of the story..stick with hybrids, gut/poly, poly/syn gut, poly/multi and closer to mid range tension and it’s all good. It’s good enough for the pros.

But that was not the case for me, or at least not with AshKev + mains.
I haven't used the Kev+ but can repeat again that Kev/ZXP plays very comfortably for me -- considerably more than full bed poly at 45-50 lbs or even poly/syn gut. Why does "naked" Kev work well? No doubt it has a very very very high stiffness rating. But, something happens after the string is tensioned, especially if you pre-stretch. Like I mentioned in an earlier post, I can get 2-4" of prestretch out of the Kev in just a few seconds with a hard pull. Is it the braiding slightly loosening allowing the slack? I don't know but perhaps this is why the first 30-45 min hitting with a freshly strung Kev/ZX racket can feel boardy....it loosens up considerably after that. And by loosen I don't mean tension drop (I think)...something else is happening.

If you do try Kev/ZXP again, I would recommend trying the pre-stretch and then also not playing with the racket until at least the next day post stringing. But, in your case I am not sure I would bother. You have a very sensitive elbow that has been injured for 1 year plus (right?). Until you find out exactly what the underlying issue is and begin the resolution/healing process I wouldn't experiment with anything outside of what you are already comfortable with. Why risk it?

This is one of the greatest benefits of this string setup -- a very consistent and long-lasting string bed. 20+ hours with no perceivable playability loss -- please name some other setups that provide this. While some may break faster (and some have 50+ hours on this setup), I personally get at least 15 hours. I have gotten much more as well -- and, like I mentioned previously you can keep reusing the ZXP if you want!

I have some ocean front property in AR I am selling. Trust me, it’s the best.
Yay! How about going on a vacation there and stop trolling this thread over and over and over? It honestly pollutes the first hand positive AND negative experiences with this setup across a variety of players. You obviously have a lot to add to the overall forum and have made your position on this thread abundantly clear, so why are you still here?
 
On another note, TW does not list the 1/2 sets of Ashaway Kevlar 16 on their site any longer. I spoke with them and you can still order it via phone (although it is currently backordered but 17g isn't).

I like the $5 half sets because I don't need to worry about measuring before starting the stringing process. But, maybe I'll use this an opportunity to buy a 360' reel along with another 200' reel of Black Monogut ZX Pro. Assuming I stay with this string setup, that will last me another 5+ years LOL
 
Out of curiosity, what kind of spin did you get with that tension set-up, and with it being very low poundage, were you still able to get decent control?
Hey ashridge

The Kevlar was extremely stable and still had snapback due to the ZX. Spin was almost equal to using Diadem Elite 18 mains which to me has the best spin including Tourbite and Cyclone 19.

My strokes look flattish but I'm getting between 1600-2600 RPM per my Zepp 2 on my forehand groundstrokes and the ball typically dips down quickly. Generally I hit between 60-70 mph on my groundstrokes unless I'm dropshotting

I got better control with Kevlar mains and a more even response, which is why I've come back to Kev mains from Cyclone 19 or Diadem 18 mains. I'll always use the Ashaway MonoGut ZX 17 as a cross no matter what mains I use

I honestly think if people gave Kevlar a good try, it would be quite popular
 
Kevlar used to be very popular in the late 80’s and early 90’s. There are 100’s of articles out about why it is not anymore. People like myself that experienced the Kevlar days see this and it’s just history repeating itself. Guess I could take the position of care a less but most people that ended up with significant shoulder, elbow, and wrist problems did so after playing with the string over a period of time not immediately. Not gonna say another word. You guys will just have take the position that everything that was experienced with Kevlar in the past and the 100’s of articles that have been written are all wrong. You have two examples of high level players on this page that the set up hurt their arm. Ominous warning people fail to heed. Take into account there are people that can play with any set up and it’s not going to bother their arm. Not the case with the majority of us humans. Good luck

I started using Kevlar to harness the power of the Wilson Profile and transitioned into a Prince Graphtech 90 using the same setup. I got used to it to a point where I really can’t use anything else. Hate the feel of poly so I don’t use those.

Ash Kev x Zyex does not play in any way shape or form like Prince's old aramid x syn gut, "Problend" hybrid.

@USPTARF97 , I'll send you free, keep it forever or..., an 80s Prince already strung with Ash Kev x Zyex or receive and send back any racket you would like to try Ash Kev x Zyex in for free. Hit it for a couple of hours and then tell the forum your thoughts.

The personal stringer for future slam champs steps up with a godfather offer!

I'll report back if I experience any problems with the Ashaway Kevlar 18/Monogut ZX 17 at 40 lbs/40lbs. So far so good for the last several weeks

I have had wrist, elbow and shoulders issues with straght poly at 50 lbs and above

You are most kind,,greatly appreciate it. How would I repay such a gift to the godfadder. Have been talking in The Godfather voice since you sent this. A most gracious offer. I can’t refuse as a horse head may appear in my bed. Forget about it..it is family..it is done..Sorry I got carried away.
Seems like Ashaway would send string for Pros to test. Anyone receive any?
Pre stretch some string and send it and will string it in a RF97 Red/Black.

@USPTARF97 , easiest is to send me a pm with your address and I will send you a racket strung with the "stuff." Burn it after you play with it, toss it in the garbage, send it back or give it to some befuddled old timer - it is just a racket and string. I would rather you try and reject the combo as only I prep and string it. I don't do extreme differentials, just like the Ash Kev at around 65lbs and the Zyex crosses at 55-58lbs. I have no interest in any other kevlar/aramid x anything combo because I have checked them out as inferior. It has to be Ash Kev x Zyex. Otherwise just string some nice fresh poly for 4-8hrs or maybe a nice Prince Syn Gut w/Duraflex for an hour of play.

Going to be hard to determine playability if it isn’t strung in a frame that I am accustomed. It could be that the frame you send I don’t care for and therefore negate my opinion of the set up.
 
I just ordered a few 1/2 sets of Ashaway Kevlar 18 to tide me over and a smalll reel of ZX as I'm running out from Tennis Warehouse. Can't wait to put it in my spare Ultra XP 100S

sigh...if you are 5.0 or UTR 11+ the racket won't matter. As old as I am I hit for fun with +10 UTRs several time a week. These guys and gals adjust in about 5 minutes or less and then we have some laughs at the crazy rackets or strings I insist that I will beat them with.
 
If USPTARF97 likes a certain weight distribution in his full poly setups, same frame strung with kev/zx would be 3-5 grams lighter and 6-10 kg-cm^2 lower sw than when strung with poly. Just throwing that out there.

No thanks, I would have to string it in my own frames to make any kind of judgment about playability. Would also string my frame around 20lbs less. Maybe 48/45. Around 10lbs less than I string Gut/poly.

Probably more likely that I will reverse the hands of father time and go from 5.0 back to open level tennis and on the road playing. Constantly looking for set ups with low string stiffness and good tension maintenance that perform. Kevlar is going in the opposite direction.
