Hi Jerry, could you explain the term 'Left thumb aft of the shaft.' for me please - many thanks Tim

When we begin, too many of us are told to put our left thumb down the top of the shaft at 12:00. In the Book it says "aft of the shaft." Yoda stated "aft of the shaft." Aft of the Shaft works for me.
Aft of the shaft would be for you to find that spot to the right of 12:00 on the grip. Personally, I think mine is pretty much at 2:30-3:00. Then pp#1 and 3 line up right behind the shaft as they should.
