7-1 Grips-Basic

The Grips of Hitters and Swingers must differ in tightness. But still per 1-L-3, 6-B-3-0-1, 7-3 and 10-6-B.

Any ideas what the reference to 10-6-B (Turned Shoulder Basic Plane Angle) is about?

I think he's saying that a soft or firm grip shouldn't affect the Clubshafts Alignments.
