Grip= Hinge Action?
 

Do you see that a 10-2-D Grip tends to produce Angled Hinging in a Swinger? Do you see that a 10-2-B Grip (Strong Single Action) tends to encourage Horizontal Hinging in a Swinger?

I think that the turned left wrist of 10-2-D is the most compatible with Angled Hinging, but I don't know if 10-2-B actually encourages Horizontal Hinging.
