Thanks for the welcome. I've actually read this site for a while just never joined.
Okay people, here's the thing with the head: the movement of the head only matters because it is a signal your body is moving laterally. Nobody strains their neck to jerk their head around, it's the body that is controlling the head. So stop moving off the ball laterally and just turn your body around your head. In the above video, the guy in the black is simply turning and tilting his spine forward toward the ball, which is moving his head toward the ball also, but which is harder to see from this angle. Stand up and do it right now; turn your shoulders, then lower your left shoulder and raise your right shoulder. If you follow this guy's advice, your spine will have the tendency to snap back to its original position on the downswing and cause different problems for you.
