I'm a 4.5 player that has always played with "Player" racquets (Prince Precision Response, PS85, HPS 6.1, iPrestige, RDS001). I've been demoing the nCode nPro Open X lately, and feel pretty good playing with it. It's a lot more powerful than what I'm used to, but I feel like I'm getting a good handle on it. My question is, if I continue improving and get to, say, 5.0 level, would this racquet be holding me back? Or are there good 5.0 level players that use lighter racquets like that one?
