Brother 12 Piece,
I am currently collecting a data base using the stroke pattern checklists in chapter 12 with my PGM Students...10-2-D is the grip of choice for many of the "diagnosed" hitters. Here's perhaps a few educated guesses;
1.) Pre-Turned Grips are usually associated with no additional rotation necessary in during Backstroke.
2.) Uncocking will perform BOTH release motions(4-D-0)
3.) Compatible with Angled Hinging Rhythm.
4.) An "adjustable clamp" which places the left thumb and line of the left wrist cock (also in line with the plane of the right wrist bend) on the Aft Side of the shaft so there can be wrist motion and hand motion in the same plane of motion...Sounds like someone could be "chopping wood" with an Axe-handle technique to me!

This grip type is excellent for those who like to get away with 'Uneducated Hands"!!!
