Grip a
straw in your RH index finger (opposite for lefties, of course). Locate it securely in the joint. Regardless of shaft butt diameter or finger length and their obvious implications, that's what

On Plane Force (1-L-#10) -- Centrifugal (Swingers) or Muscular (Hitters) -- that is likewise
On Plane and (through Impact) directly
BEHIND (and in total support of) the Shaft.
