Hey Alex,
Yes just realised this was the first post you made regarding the backhand topspin. I think the video here is ok but not as smooth and relaxed as the other version which I answered you back on before.
As you said the additional body turn and slightly different swing action which is helping you create a better quality of shot. I feel in the version here you aren’t getting the maximum use of the wrist, compared to the other video where you are really getting a quality acceleration through the ball and good grip in the ball. So definitely stuck with that second version as it looks a lot more comfortable and correct to us.
Dan 🙂
