Actually, finishing over the shoulder means a flatter shot. The around the waist follow through means it was a windshield wiper follow through, which means the racket didn't drive through the ball as much, meaning a more severe brushing motion, which equals more top spin. Yes, generally speaking, the big hitters on the WTA hit a much flatter ball than their counterparts on the ATP. You really don't see anybody on the ATP who hits as flat as Davenport, Sharapova, Venus, and etc. Maybe Berdych's forehand. Not anymore anyways. Maybe 20 years ago there were a lot of guys who hit as flat as the present day WTA.
