tfm - Have not hit a ball in 5 weeks, and its killing me. Especially w/ all the tennis that's been on TV. And if you think the super heavy/stiff racket is bad, I used to use Kevlar / Synthetic strung in the mid 60s. However, the only arm problems I had came from bad technique on the serve (which is why my take back is more like Rafter's). Since I fixed that 8 years ago, I've had no problems whatsoever.
Sup - I have no problem paying a few $ to get a racket measured, but I would like it to be somewhat accurate as I'm going to use those numbers in my next racket purchase (if I go w/ Vantage).
