has anyone else noticed this? does your racket feel different after you have had a big clash with it? when you play a game and doing ok, and then one of those "OMG, this is it" type of clash happens, you look at your beloved racket, and despite a big paint chip it was completely alright. but for the rest of the day and beyond, the racket don't play like it did anymore. i have had a few people who mentioned that to me and i also have felt that before with my own rackets. is it just psychological? or can there be something real about this?
