OK my leg was still a bit sore, but since I took my son out for lessons, I borrowed his basket of balls and had a hit. I was concentrating on loosening up the arm and upper body rotation. Was surprised at the easyacces to power and spin, and I did get into quite a groove. I was also getting used to the new trajectory of the ball. Good net clearance, compared to my classic stroke where I would hit it much closer to the net.
I still end up pretty high on the follow through though. I suppose while my arm is looser than before, its still not loose enough?
Sorry if the video is a bit long, wanted to show the groove I was in.
