Too much information. I understand why when people ask top player how they hit the ball, they usually say "I just hit it". The whole tennis instruction concept is completely backward.
When you make the ball travel to where you wanted in a certain speed, your stroke will look pro-ish to the 3rd person.
Just go out there and hit the ball for christ's sake.
