Ian - good points. I think the extensor action may be part of the issue. He did tell me he feels like he's "gator-arming" it and he may just be getting lazy with the right arm. I'm going to pass that on and see if it has any effect.
Edz - he does work on a pretty steep angle. He went from playing a draw to hitting mostly fades a good part of last season (when he was playing his best). To Ian's point he may be overdoing the feeling of having the clubhead move from out to in.
