I've played all my life with platform; decent serve, good flat first, so and so 2nd (a lot of time spent to improve that kick/topspin serve!). Today I tried just for fun to serve using the pinpoint: whow! I'm not impressed at all by any change in the pace (actually, I can't serve a flat bomb with pinpoint stance), but the amount of spin I'm able to impart is much bigger, and so is the "heaviness" of the ball with better %. In addition (I can't explain why) it seems I'm forced to hit the 2nd serve with more pace and spin, and it's working. Anyone did the same test? What do you think?
