Your preparing to return a forehand hit from your opponent and the ball hits bounce up where you can not drop the racquet head and swing through with topspin(low to high). You have positioned yourself and you have no choice but to hit it now! It is up fairly high...I have to hit it flat with no topspin. Question - How high does the ball have to bounce up for you to flatten out and drive thru the return. Net high, higher or lower than the net? How do you decide?
