The second is a four-sided sign stake that is shorter and gripped normally. I use this to heighten the visual and kinesthetic sense of 'Aft' -- behind the Shaft -- Pressure Points (the Left Thumb, last three fingers of the Left Hand and pad of the Right Forefinger).
Yoda, thanks for the input. Will try to pick up some 'sticks' in the next couple of days. I had 1 question regarding what you said in the quote above. I have seen a lot of post referring to the left thumb on the aft side of the shaft, but I am having trouble picturing this. Using the 4 sided sign stake as a reference, would this put my thumb on the right side looking down at address (side directly away from the target) or would it actually put it on the opposite side? I am just starting to get used to applying PP1 on my left thumb, would this change the feeling of the pressure point since my left thumb would be behind the shaft?
