Ok, first off again I would like to apologize if this has already been discussed before. Please don't hassel me about it thanks! Ok in a lot of posts i've read everyone says wilson doing a bad job of customizing federer's racket or they have strung his rackets exetra. So my one question is...what racket is he using? Is he using the prostaff 6.0? Is he using the prostaff tour? Is he using the ncode? Is he using the kfactor? Thanks!
