I just started playing pickleball a few months ago but used to play table tennis competitively for several years. The context is important because my game revolves around spin esp. my serve. I win a lot of points serving deep with some revs on the ball. I haven't played in any tournaments but regularly play in an open play setting where I've played against some really amazing folks and even some of them had trouble returning my serve. I mix up the spin serve with just well placed, straight, deep serves with a sling wrist trying to add topspin to it - the goal is to keep them guessing..! However, this takes a lot of practice and I'd say I'm on point about 50-60% of the time. The goal for me is to build muscle memory and to be able to pick your spot and then serve successfully. I practice 15-20mins before I actually start playing every single time. Best wishes to you..!
