I was contemplating sticking this under the health forum, but i decided to go here cuz I had some other string question. To the point, I've had wrist problems for the last month, and now my whole arm is getting sore. I switched to Kevlar about...I think 6 months ago, but didn't have a problem then. I just thought of this. Is Kevlar why I have my wrist/arm problems? Also, is poly softer/easier on the arm than kevlar? I'm gonna guess it is, haha. My current string setup is Kevlar 16gauge (with some sort of coating) @ 59lbs, crosses syn.gut 16gauge @ 59lbs I'm probably going to swap out the kevlar with Gosen poly 16gauge, will I feel a difference in terms of feel/"crispness" i guess? Uhh, not as dead as kevlar. I've never tried poly before. Thanks guys Oh yeah, I forgot to say I break strings often. kevlar lasts a week. That's why I switched to it in the first place. EDIT: K, I think I'm going to try Gosen Polyon Comfort 17 and Gosen Jim Courier 16. Does anyone have experience with these two?
