That is fair. I think the bias stems in part from the fact that people who use so-called "players' racquets" generally speaking have a more relaxed-looking game: you don't see Federer looking like he's just finished a 12-rep set of 50 lb. curls.... By the way, was it by any chance arm pain that made you switch?
Even more by the way, I noticed you have some posts regarding PC600's for sale. Are those still accurate because I'm interested!
