Yes, the man is the Wimbledon champ and #1 in the world, but I still think Roger would benefit from switching to a slightly bigger headsize. It isn't made any more evident when you see the tremendous amount of errors coming off his racquet on a regular basis. If he doesn't like the Six.One 95 of Pro Staff Six.One 95 frames, he could always work with Wilson on creating a whole new signature frame just for him that incorporates the 95 sq. inch head size. In all likelihood it would be a huge cash cow for Wilson as well as benefit Roger's game.
Just my 2 cents.
