K back to Horizontal Hinging........

-you need it for total compression.
-it feels like a roll. But you need to ask yourself how much of a roll. Not too much or too little. There is an Alignment that'll make this clear.
-it is the opposite of the ill founded but common , "seems as if" logic that the clubhead should remain square to the hole for a straight shot. Steering , Vertical Hinging. High floater shots resulting.
-research its Associated Basic Plane ......it'll take a while but it'll make sense , total sense in the end. Closing with no Layback it has an advantage......in a totally compressed ball.
