I've been reading some of these threads, and I'm a bit confused on how some of you can have 2 or 3 different sticks in your bag during a match. Maybe I'm a head case, but I have 4 Babolat Pure Control + "2001" rackets, all weighted the same, all strung with the same string, at the same tension. I use the same overgrip, as well as string dampener, etc. The reasoning is: If I hit the ball out, it was something I did. Its not the racket. Its not the string/tension. Its not the overgrip. Therefore, if I'm missing shots I normally don't miss, the only variable in the equation is me. Am I crazy?
