Yes, I think we would be saying the same thing. The left thumb should be in the cup of the right hand. The #1 pressure point (Spiderman's web shooter for all you non TGM'ers) should be on the side of the base/1st knuckle closest to the wrist not the nail.
Length of the left thumb on the club influences #1PP location...
This most influences by the distance the index finger is seperated from the middle finger...changing one requires a change of the other in location on the club
Andy Bean - Long Thumb
Jack Nicklaus - Medium Thumb
Sam Snead - Short Thumb
This influences the Range of Motion of the #2 Accumulator...and it's the opposite of what "Academy Live" says....
