I happen to have had a lesson today with Mr. Doyle at the Quail Lodge. He is doing quite well and worked with me a couple of hours.
During the leson I asked him about the aiming point. He took out a small chunk of turf near my left foot and said that was the aiming point. I asked about #3 pp, and he stated that was to monitor lag and direct the club head to the inside aft of the ball.
I am having a playing lesson with him tomorrow and will be happy to follow up if anyone has any questions arising out of what he said.
Naturally, working wth Ben is a great joy. Signed my Golf Machine Book. Going to his house tomorrow and play his par three course and meet his wife.
that's a cool think to be doing, i'd certainly be interested in hearing how it went & what you picked up from it
