what are the pros/cons of kevlar strings itself and hybriding it with poly/synthetic gut.
what are the pros/cons of kevlar strings itself and hybriding it with poly/synthetic gut.
Kevlar can only be used with synthetic gut, unless you enjoy killing your arm.
It MUST MUST MUST be tensioned below 50 lbs. This hybrid is extremely stiff, I don't even use a damp on my racquet right now. Currently its strung at 48, and even that is still stiff.
Pro's? Spin and control. The spin is better than most poly's will give you, and its low-powered so you get extra control.
The only pro for kevlar or aramid is tension maintenance and this is comparing it against the main alternative, poly.
The rest are all cons when compared to poly strings ...
Poly's have better playability, are less damaging to the arm. Both have great durability and are difficult to string since stiff and hard on the fingers. I dont know why anybody would still consider using kevlar when there are soo many good poly choices ? Most pros have even gone to poly or poly/gut.

The spin and dwell time is amazing with full bed kevlar@40 pounds. Also there is no shock at all to your arm. Very dampened feel.
Everyone needs to try it at least once. The feel is completely different than any other string setup out there.
I use Ashaway Crossfire, 17 w/60lbs on main, 16 w/65lbs on cross, it's fine so far...

kevlar is neither good for you arm or your frame
On the other hand it can very bad on your arm if not used properly, pretty dead in feel, kills almost everything else if used in a cross.
Poly's have better playability, are less damaging to the arm.
Cons: It will really do some damage to your arm.
Drakulie,
I agree 100%.
I still play with Kevlar, I started using Kevlar after a severe case of Tennis Elbow (yes you guys got right) and I have no pain at all.
Polys cause more disconfort in my opinion thatn Kevlar
I played with kevlar for a long time. In fact I didn't even know what kevlar was really, I just used it because it was available to me and it didn't break easily. Which meant spending less time using the stringing machine with this creepy guy hanging around but that is another story. I never had arm problems with it. The brand I used was Forten. I combined it with wilson or prince synthetic gut.
I agree... but even at super low tension... it still hurts the arm.
I don't think the material is very good at dampening natural vibrations.
The main advantage to Kevlar is durability. I was trying to cut some string out of a racket and the shears were twisting rather than cutting through the stuff: Kevlar!
Agassi used to play with Kevlar, but once he tried Luxilon, he quit playing kevlar and switched over because the poly gave him more spin.
BTW.. Agassi also blew out his wrist using Kelvar. Just the facts.
The obvious cons are stiffness (which could lead to injury) and lack of "feel".
I played with a kevlar/syn gut hybrid for about two years and never had a problem with injuries. But, I did get injured using poly and had to take 6 weeks off. Though it was the particular poly (Luxilon BB), not poly in general. I switched to a different poly and everything was fine.

Only tennis injury (arm, wrist, shoulder, etc) for me. Kevlar. Once I had my own stringer, never used it again. I am sure many have used it without injury..for me not on my list for safe and long-term arm health. Of course that is just me.
To each his own...heck there are players here using ALU Power at 70#s on a 14 oz K90 without injury.

one thing i dont like about kevlar is it just totally thrashes your grommets
it will actually saw through them pretty fast, and i have to replace them a lot more frequently then i do with any other type of string...
Btw guys,
Anyone here know the longevity of Forten 18 Aramid? I've been playing with if for bout 10 hrs already n there is slight notching from the Forten sweet 17 but nothing significant. I'm more concerned bout it going dead?
I heard from my stringer that shock absorption is nil when the string goes dead so roughly how long can I play this string before it dies?

i used it for about 5 hours and got heavy nothing on the mains. i'd imagine i'll break it within the next 2 or 3 sessions. but i cut them at that point to test other strings. as far as feel, it still feels good only a little bit more muted and the strings will start moving around so much more. i strung it at 54/59. if i get another chance to use it, i'll string it lower around 50/55 or 52/57 tho.
Agreed.
I seriously think some posters write about things they have no experience with.
Kevlar, for those who enjoy the feel provided is a great string.
It offers absolutely amazing control, very good spin, and is extremely durable. Additionally, once it breaks in, the comfort is very good, because it absorbs so much of the ball impact, resulting in less stress/vibration to the arm. (this is contrary to what posters here are saying).
I love my Ashaway Kevlar 18g (48# M) and any synthetic gut 17g (50# X) hybrid. But I have recently run out of my kevlar reel (don't know what to do with the remaining 15 feet, sight.) I now have a bunch of 1.10 - 1.20 mm co-poly that are soft. Can anyone suggest how I might hybrid these with synthetic gut or something to get a similar feel to that of the kevlar hybrid?
BTW, the kevlar/S.G. combo plays like a dream (if you like control, spin, drop shot, and that dead feel) and doesn't hurt my elbow at all. The co-poly I have seems to be too lively for me to like so far.
I highly recommend that you try this setup:
Ashaway Kevlar 18g Mains @ 45#
1.10mm co-poly Crosses @ 48#
...and come back and tell me how it compares to your Kevlar/syngut setup.
