how do the pros get topspin when they pronate on serves?
im trying to learn to pronate, but i can't imagine how to get topspin.seems like pronating just helps you hit a super fast flat serve.
where exactly during the serving motion is the strings brushing up on the ball, before the pronation?
this video says it's harder to get spin with the pronating finish than the "dirty diaper" finish
i have the "dirty diaper" finish
i would experiment and practice on my own, but it's winter and the nearest indoor courts are over an hour a way.
