I haven't really had any time to practise this but I shall be making a lot of slow swings trying to get a feel for it. Then I'll take it to 50% speed and see if I can make some changes. It was only something mentioned for a few seconds in my last session with Brian.
Yes, this is the one thing I think that makes my swing look more ugly than it needs to. I know I have always had this move. Someone correct me if I'm wrong but I don't think it would come high up on the list of things to work on. I doubt I would gain much by trying to clean it up.
Also I would bet a lot of money that trying to clean up my neck moving around as it does would be super hard. But I'll get round to it eventually as it does look silly
