So, my serve is a big weapon, and my overhead is a big weakness. Sometimes I whiff entirely, but often I just get a piece of it, mishit it, or hit it with weird unintentional spin. I can do flat and kick serves fine and with good form, continental grip. How does one hit an overhead ideally? Is it basically the same thing as a serve only on a different court location, only accounting for the different arc and height of the incoming ball? Or is there something I'm missing... I try to keep my non-hitting hand up, keep my eye on the ball, and position my self in the right spot for the downward coming ball, but I still am so inconsistent. Drills and more drills to practice this are clearly in order, but some technical and explanatory tips surely will be of benefit for me!
