I also was curious about how closed the clubhead appeared to be on the back swing. This is something I have been trying to change, maybe I'm on the wrong track??
I'll let Ted comment further on his Clubface alignment, but remember...
The Hitter using Angled Hinging aligns the Clubface Closed at Impact Fix (2-J-1). It therefore should come as no surprise that the Closed alignment is maintained throughout the Stroke.
I'll have to agree with my mentor, and most importantly with this shorter club, the clubface should look a little closed. With the ball position being placed farther away from low point and making the clubface square as I assume my impact fix and impact address, the shorter clubs have to look closed. I'm touching the ball well before low point. As I move the ball position forward for the longer clubs, the clubface would not look as closed.
