I know a person who strung Rogers sticks early this year and last year and Federer does indeed use the tour 90. Im not sure if he is going to use the real ncode, but I know for a fact that Federer does use the Tour 90, his is just alittle modififed. With the handle being abit shorter. His racket is also pretty close to even balance. He also uses a very small handle like 4 3/8 pr 4 1/8 dont remember So there you go.
