This should go a long way in disproving the myth that great servers hit the ball near the peak of the toss. I got the link from one of Marius_Hancu's sticky posts: http://www.uspta.com/html/e-lesson-Flat serve.swf This is a great video clip for examining the toss height. The slow motion video stops once at the peak of the toss and and again just before he hits it. The difference in height looks MORE THAN A RACKET LENGTH !! I am kind of glad, because whenever I tried to hit inches below the peak, I had to hurry ridiculously and messed it up completely. It looks impossible to have a modern service motion(full knee bend and push off where the toes leave the ground by several inches) and not toss it high. Is there anyone who thinks they hit the serve close to the peak, and use their knees fully? I think if they videotape themselves, they are in for a surprise. Either they must hit well below peak of the toss or they are mostly using their upper body only, thus making the service motion quicker to execute.
