Effect of short pimples

Hi sir,

What is effect of short pimple rubber like long pimple generates reverse (underspin to top spin and top spin to underspin )

Thanks sir.

Hi Kedar,

The Short pimples flattens out the spin on the ball.  If you play with topspin it will still come back with topspin but it will have less topspin.  The ball will tend to stay a bit lower.  It may even feel like it has backspin but it will still have topspin, just less of it.
