I'm realizing just how much 40 years of shifting and lifting is ingrained in me. Even when trying to swing what feels like a 2/3 backswing, I am lifting my arms (see down the line view). A stubborn problem I'm having is that my hands are way behind my body at impact, and I end up scooping (see the face-on view). Is it possible that shortening the backswing, with less lift, could help time my arms with my lower body better at impact?
I actually think your arm is in a very good position. From the face on view, obviously your arms are behind your body. More than likely, just too quick of a transition. You want the weight shift and your arms starting back down to happen in sync.
