I would appreciate any feedback you might have. I am a 40something 4.0 male player who took up the game five years ago, using a Dunlop Adrenalin Rush strung at mid-range (60lbs.) with Prince Duraflex 16. This November, after the Rush seemed to have gone "flat" after numerous restrings, I bought a Cat4 and strung it with the same string at mid-range(53 lbs.) I began to have wrist and elbow pain after about two weeks (the wrist pain came first, then the elbow and nothing about my technique or amount of time on court or balls used changed.) I got a POG oversize and started playing with it a week ago and there is no extra post-match pain and the residual wrist and elbow pain are almost gone.Has anyone else experienced pain after switching to a Cat4? I noticed one such post on the Volkl leave-feedback page under the original Cat4 on the racquets page. Thanks in advance.
