these are the conclusions i have got after i had done a study on the penhold and shakehand grip. please tell me if iam right.

PENHOLD

*YO HAVE A CROSSOVER POINT BETWEEN WHETHER TO USE KOREAN JAPANESE BACKHAND OR REVERSE PENHOLD.

*LESS COCHES TEACHING THIS GRIP.

*CANNOT EASILY DO A TOPSPIN WITHOUT SIDESPIN IN REVERSE PENHOLD.

SHAKEHAND GRIP
