[Mathew]

My off the wall tip - to try for Matthew - if not real at least perceived would be to start at address with hands facing each other- then at the top with the left wrist slight cupped feeling- and looking- have the right wrist at 90 degrees (perpendicular) to the left wrist. Before anyone freaks out- that's a lesson tee thought- experiment- application- etc. and a possible X classification. You can actually twist the hands on the grip enough to accomplish that.

Are you describing changing the 10-2-B grip into the C variation whilst preforming the standard wrist action?

Is this the rotating lag pressure point as mentioned in 10-11-0-3?
