#2 and #4 are the pressure points the book advises focus on for swingers. One thing messed me up, I tried to create pressure on those points. The centrifugal force of the swinger will cause pressure to be applied at #2. If you squeeze those last three fingers, you could have problems squaring the club face. I try to make sure it is the swinging motion that puts pressure on those fingers. Monitor pressure points, do not create them artificially.
thank you that makes sense. I believe Im doing the same. That helps sort some things out in my mind. Having trouble w/ as you say creating these pressure points artifically Im sure of it. I was confused w/ fact I guess if youre pulling w/ upper left arm how could you create pressure at pp#2 w/out altering club desired path from centrifugal force.
