Hey guys!, Idk if you found this out but i just did so i was looking online of Roger Federer pictures of this year 2013 and i saw something interesting. As you see Rogers Racket is completely different from the TW american version you see online It more similar to the Europe TW version if u check online!. The paint the same but design is different with the wilson on both sides in the middle, ninety name, on the gold side of the throat had pro staff 90. MAYBE it has a different in weight. Also he been using the Europe this whole year so far.Even in the BNP Paribas open BUT!!!!!! Then i saw this photo of 2012! You see him using the US TW version. SO! does federer switch between the american and europe version? is there a differences in weight? just interesting to me Any information helpful! THANK YOU!
