Okay, so I recently posted a thread asking how to hit sidespin. Sorry for posting practically the same thing again, but I now realize what I actually wanted to learn was spiral spin. Can anybody tell me how to hit spiral spin when returning balls that have lots of pace (such as serves)? When hitting with my 7-year old brother, I was able to produce spiral spin, because every ball he hit was flat, and very slow, but I don't know how to replicate this when I hit a ball that is traveling rapidly toward me, or a ball that has topspin or backspin on it, etc. Can anybody help me hit spiral spin?
