lets see if you are actually doing what is taught, or something else.
Maybe in trying to do MGS you are really doing something else, but that something else is better then your old swing.
The question I would have is what happens when you swing exactly as directed? Not some in between swing.
I have seen no pictures or video of an improved impact position after switching to MGS. I have an open mind, and have tried the swing for fun a bit myself.
I just like dealing with facts, not what someone feels. Feel fools you in golf. I see it everyday.
DO NOT MISTAKE this to say that you should stop doing what you are doing. If you hare happy with your results NEVER change.
