The Moe Norman swing is deceptively simple. There are many subtleties that you can not pick up on in just watching old videos. Ball position, club at address, grip, shoulders, proper weight shift... on and on. The main reason that this swing is not used more is because there is only one guy teaching it. It does become very consistent once you "get it". But so is any swing. The day someone wins a major tournament using the single plane swing - that is when everyone starts promoting it on their platform as "the greatest thing ever" - since Moe Norman. I will say that anyone that has back or mobility issues should look into it because it is very easy on the back and joints. You are not cranking your back in your backswing rotation - in fact if you go too far back it throws off the timing completely.
