I play with the FlexPoint 4, which is quite a racquet similar to Venus'. They feel that they can still control the ball with their muscles and they can afford to hit off-center shots at times. The only problem I have with these racquets if that when the going gets tight in matches, they lose confidence in their swings because they have no idea how the ball is going to react off their swings. If you hit through the ball with those raquets and have good technique, the ball will stay it. I don't have their racquet-head speed, but my FlexPoint 4 has helped me a ton on my serve speed and my groundstroke speed. With my Head LM Instinct, I could hit at hard, but it wasn't that easy. I sometimes train with my Instinct to keep my racquet head speed up on my FlexPoint 4.
