I have seen people at a higher level play, and I even played one recently, and I all notice, they hit the ball with lots of spin and the balls go high. How do they make it hit so high? It doesn't seem like they are hitting hard, what spot do they hit the ball at? Even the kick serve went pretty high, and my friend played someone who's kick serve went over his head (he even smashed back a return and it went in). Since I'm not used to high balls or playing at that level, I got double bagled. So basically I'm just wondering, how do they get the balls that high up?
