Ping Pong serve is the best way to see that spin is in.The Chinese here in Fullerton are big on Ping Pong.I know I play them and lose.TreBert PS My friend Hoo can beat anyone you know.TreBert

How is tennis ball spin different and "Mind-Bending" when compared
to baseball spin, golf ball spin, cannon ball spin, or any other
ball's spin, spamming shit head?

Are tennis balls magic, spamming shit head?

   Now now, jimp, it sounds to me like you are still having another
   bad weekend. There is something you can do about that in your area:

Are tennis balls magic, spamming shit head?

What is the magic quality of tennis balls that separates them from
baseballs, ping-pong ball, golf balls, or any other ball that
produces "Mind-Bending Physics", spamming shit head?

There is nothing in the article about the magical and special qualities
of tennis balls as opposed to any other type of ball, spamming shit head,
and now lier, spamming shit head.

There's a fully developed tennis topspin and a simpler goofy topspin.

The fully developed tennis topspin uses a slower stroke than natural but begins the stoke sooner. Then the stroke first pushes the ball forward and than adds topspin simply with the follow-through. Also, this slower stroke makes it possible to get anything on the racket and under control and that's like when slice is being hit to the player.

The simpler goofy tennis topspin is just a fast snapping stroke with as much upward motion as forward motion.
