So other than playing ping pong, I don't have any other racquet sports background. I can put topspin on the ball when dinking cross-court, but have trouble figuring out how to drill/practice topspin volleys or other "roll shots." Watching videos of the pros do it, alas, doesn't seem to help.
Anyone with racquet backgrounds have advice for those of us without that foundation on how to get better at topspin? Are there pickleball tutor/lobster/machine drills that would help?
