Overhead and backhand

Couple of quick notes after watching a bit of the Wimbledon final (Federer-Roddick):

• On a warmup, I watched Federer hit overheads. I was surprised to see that the setup is the same as for the forehand I described earlier: he held the racquet with the left hand and turned his shoulders, arms, and body as a unit, then released the left hand as the racquet arm started going forward. No pointing with the left arm towards the ball; instead, it's a forehand that is turned up.
• On a backhand, he has a smooth elliptical move: as he tracks down the ball, he turned arms connected at the racquet and body as a unit, with the racquet going in an upward arc, slightly above his head, then going down and low over the court towards the ball. He steps into the shot with his right foot, and finishes with little or no weight on the left foot. Unlike the forehand where he pushes off with the right foot, it almost looks like he's absorbing the body's momentum into the bent knee of the right leg. When I started consciously bending the right knee as I move into the shots, backhands came out better.
