Thanks for the thought of starting by getting the left hand vertical--I can relate to that--I assume that means at impact fix with the clubface slightly open to the target line and shaft leaning forward..I guess it would work at address position as well---as far as aft goes there are 180 degrees of aft---if we are looking at a clock, where on the 12-6 clock would the left thumb and #3 pressure point be located ?

#3 pressure point is at 3:00 or 90 degrees (only position available for normal force) to the vertical plane of the left arm flying wedge. The left thumb should be in the area of 1:00 to 2:00 with the pad of the thumb on the shaft.
