I know there used to be a thread on how to do a slice properly, but I couldn't find it. I can't generate hardly any of my own pace using a slice. It seems like the only way to control it for me is to have pretty low racquet head speed. This has led to easy balls for my opponents, or even balls going too short. when I speed up my racquet it seems to pop up really high. What is the proper way to hit and follow through with the slice?
