not a fan of the back and forth swing, but still valid."
When I read that, I thought "I don't do that, I only do a single backswing." Then I watched the video again. Ah. Right, okay. In my practices, I'm in the habit of starting with my hand quite far forwards, and beginning the backswing from there. It seems in his case I've been moving into the forwards position and then immediately starting the backswing, which does make it a "back and forth". So thanks for calling me out on that, and also for letting me off. I shall make a point of starting from a still position in future! Cheers.
