Anyone ever noticed the setup and backswing on Federer's backhand? I was watching a bunch of video highlights of his BH (slice or topspin, it really didn't matter), he kept taking his racquet back in a vertical position and would lightly hold the throat with his left hand. I just thought this was kinda odd, as the starting position to hit a BH. (I'm certainly not criticizing it, it's an excellent BH by all estimations.) Looks a little odd, but maybe I'll even try it myself. Maybe he's onto something.
