The picture is at A2. A3 is when the hinge happens. Even if he doesn't have a full hinge at the top of his backswing, I bet it still increases in the downswing. 300 yard drives with minimal hinge doesn't exist as far as I know.
Two things: first, I would not change from one model to another for 1 yard; nor would I say one is more superior than the other. Secondly, the further the hands travel on an arc the more speed you should get, all things being equal in your swing.
I don't think pros have a preference, their bodies and swing styles and mechanics probably choose oNE or two plane for them.
