[O.B.Left]

You can only Hinge and Trace so much. Through impact really. Assuming Horizontal Hinging say, you need something to get your Left Palm off the Inclined Plane and over to a place where it is perpendicular to the Horizontal Basic Plane.

For some it is a feeling of a long continuous Swivel. You cant align a long continuos Hinge Action for full swings. You can only align the Left Hand perpendicular to a Basic Plane whilst aligning the shaft or sweetspot to the Plane Line for so long. Short shots you can do it, it is the ideal, in fact. But not long.
