Classifying the other grips as inferror I don't believe is correct. They are valid.
In fact if you take Mr. Kelley at his word regarding GRIPS, he encourages a golfer to adjust the grip for better direction (10-2-0). In that section he defines the relationship of the hands to each other or the ground.
Regarding the Fly Wedges, it is time for me to incubate. Plane of Left Wristcock and Plane of the Right Wrist Bend. The Forearms and clubshaft to those planes. Not sure the others can't support the above relationships.
I would suggest caution when attempting to define relationships of the grips to flying wedges in regard to pp#3.
More thought needed.
But I don't beleive that it is correct ot classify them as inferror, nor are they necessary a disadvantage mechanically necessarily.
