Where on the base of the thumb should pp#1 be located?
Should it be over the bone indicated by the cross hatch, or is it OK to have it a little farther out over the joint. Because of the position of the thumb on the grip, using an overlapping grip,I find my pp#1 has a little give in it when pressing down across the shaft. Should this be the case?
I believe Scottgas2 is after a more precise answer regarding the position of the heel of the Right Hand where it touches the Left Hand thumb. Is it possible to put a cross on the image he has provided indicating the center of the #1 Pressure Point when using a 10-2-B grip?
Taking the grip in impact fix alignments?
Right hand palm grip covering the base of the left thumb? Or turned under?
Overlap, single or multiple, interlock, reverse overlap, non-overlap?
Tight grip?
It varies by person.
The actual instruction is that PP#3 in line with the sweetspot defines "strong". And "Unless otherwise indicated, the left thumb is always placed on the same line as PP#3 and covered with the cup of the right hand palm. The thumb position encourages the ideal right wrist bend - identical to the accumulator #3 angle."
A hitter might want to try the 10-2-D grip which has "the left wrist turned to the top of the shaft so that wrist cocking motion is on the same line as the right wrist bend. The #3 pressure point and the left thumb are also on the same line as the right wrist bend. Strong double action."
Same as 10-2-C weak double-action for swingers, where the right wrist is rolled to the top and PP#3 is no longer in line with the sweet spot.
But according to the book the 10-2-B is the only one that will preserve the Flying Wedges.
