With all these threads about federer needs to change to a bigger raquet (which are BS) . I think he could do with a string / set-up / tension change. Personally i would like to see Fed try using a full poly or even change to poly mains with gut crosses. He is really missing that forehand that he used to rely on. With full poly it could help get so more control and the added spin might help too, it could also help with the backhand when he plays the likes of nadal . He also hardly ever comes into net now so he will not miss the added feel of gut mains! What do you guys think?
