Been playing for 40-years. 13-handicap. 75-years young. My natural ball flight has been a draw. Always able to tee up at the left block and aim for the right side of fairway. Most times hit it pretty much in the center of fairway. Been fighting a pull hook for the past couple of weeks and kept trying to prevent coming over the top with active hands. Yesterday on the 15th hole had a thought about spine angle. Bent over a little more at the hips, hit it 230 dead center. Kept repeating that set-up and the pull hook was gone. None of my playing partners picked up that I was standing taller than normal.
