Good Luck buying Fed's exact racquet in a store. Since he won't allow the exact specs to even be known how do you suppose you're going to find his exact racquet?
BTW. In this German tennismagazin of december 2003. I know it's long time ago but i think it has some valuable information has the specifics of Federer's racket at that time.
The weight of his racket is 355 grams and the balance point is 31,7 cm. On clay his weight is 362g(32,1 cm) On grass 355 g(31,7) Hardcourt 358 g(31,9) and in Halle, A grass tournament in Germany his racket weighted 360 g and the balance point was 31,8 cm
As you see he changes his set-up but the changes are minor like any pro.
He played the same racket he uses now and the headsize is 580,5 cm.
