thing happened to me when I switched to NG. In learning NG I was almost immediately better, and played some fantastic golf. Even almost qualified for the British Open. That was a few months after changing to NG. As I continued to work on the swing elements to make it even better (face the ball at impact, palm grip, wide stance, etc....) my golf got continually worse. Until I reached the conclusion that NG/Moe worked best with a CG swing/grip and NG setup.
Kind of like what you are saying with MGS. Get the setup and forget the details of the swing. Going to give that idea a try when I get a chance. Maybe tomorrow.
