Topspin stroke

In harimoto’s backhand, you sad he can do the ‘deadly down the line stroke’ but it’s below shoulder height.

Is it okay to do below shoulder height because it works for him.

Does it work with forehand as well

Hi,

Yes the backhand can be more forward as you are using a lot of wrist to generate topspin on the ball and he is playing against a ball that already has a lot of topspin on it from his opponent.
