Pimple Rubber

Please how can i differentiate between long pimple and short pimple rubbers?

Hi Ene,

It would be good if you have them side by side for easy comparison.  Firstly if you touch them you will feel that the long pimples are softer and have more wobble when you push at them.  The short pimples will feel firmer.

When you play against them the long pimples will slow the ball down and reverse the spin on the ball.  The short pimples will flatten out the spin but will not reverse the spin.  The short pimples comes through quite fast.
