John: A number of the top pros (including Federer) have the face of their racquets closed at the bottom of the downswing on the forehand. What do you think the effect of the closed face is at this point in the swing? Also, have you determined the wrist angle relative to the forearm of the top players from the top of the forehand stroke to the bottom of the downswing. Some observers have said the angle is about 30-45 degrees and remains constant as the arm drops to the bottom of the downswing, while others have stated that the wrist remains in a "neutral" position.
