Thanks Bernt for posting these.
I was in Phonenix couple months ago and took two lessions from Greg Smith. He looked at my swing and suggested trying right forearm takeaway. All I did was to pull to the top and let go from there and change was dramatic to the better. That and some other things Greg gave me to work on helped a lot.
Once I saw Allison's presentation, I knew why that RFT worked so well - I was pulling myself around, not trying to push (I really had a dysfunctional pivot).
I've now also worked on pulling myself around on downswing as well and things keep getting better.
