Turning the bat with one sided pimples

You are recommending defending with long pimples in some videos. Many bats have the pimples only on one side (mostly the one used as backhand side). Now is it still advisable to learn turning the bat during the exchange of shots, i.e. after the serve? My impression is, that higher legue players (Joo se Hyuk) don't practice this often. Nevertheless they defend well with their non-pimple side, so why use pimples in the first place?

Hi Herbert,

The pimple allows better control when defending faster shots.  The better defenders tend to attack a lot with their forehands and mainly defend with their backhands.  If they do attack with the backhand they will sometimes twiddle to make a topspin attack.

Using it on their backhand means that they don't have to turn as far and if caught in front of the body where it is more difficult to control the ball they can still control with the pimples.

They do tend to twiddle early in the rally on pushes but only use it as a variation.
