Spring loading the pinkie

 This is not tennis, his is a lab apparatus using tennis tools. It is about the three fingered grasp, scoot the pinkie underneath the butt of the racket.  I report the latest results.

Thew grasp will spring load the pi kie, it acts like an energy storage sprin g.

And, the grasp acts like you have a ball joint, articulated, at the butt of the racket.   The racket is not going to fly lose, and a jerk of the hand gets you between continental or western, all three finger mode.  Increased speed or precision by 10%, I think.
