Thanks, Curiosity. I have increased my loop size since I posted my videos, as part of my forehand improvement efforts, and the bigger loop/backswing has helped greatly in the power/spin department. I am now adding the straight arm/ESR component to it. The challenge is going to be the matching footwork, to create the spacing necessary and reacting quickly to the ball - lots of old muscle memory to be erased and replaced!
