that's very different that what larry teaches in person.the release is definately not activated by adjusting your fingers, only by squeezing a certain muscle in your back (what the heck is the name of it?), which in turnmoves your elbow perp to the arrow, thus changing the angle of the hook you've turned your fingers into, and letting the execution happen. its all about getting away from finger movement.

oh, larryaims,and useshis rhomboid (is that it?, i'm not getting my book out, i can point at it) subconc. but says others do it opposite.
