I was thinking about this on the way to work. I should probably seek psychological help. But whatever gets you through the night.
How about getting a short club or dowel. Then set your impact bag on a low bench, table, stool, dog, cat whatever. Pound the bag as usual placed at impact and follow through per your expert advice. My thoughts were that you could really focus on the critical Hand alignments and how they translate to the Clubhead and Clubface with a short club. The Impact Interval could really be right below your nose.
Does this sound like a winner or a loser for a close up and intense alignment drill?
