Lynn/Yoda/Holeinone:

Congratulations on the new site. We are all very eagerly awaiting the evolution of your site. I wish you the best of luck with the new venture. I know we in the golf world will all benefit from it.

My question is about the position of the left thumb on the grip when hitting. I seem to have a difficult time comfortably placing the thumb on the aft side of the shaft. When I do this and relax my forearms the clubface is very closed. Am I doing something wrong or can I use a more neutral left hand possition with my thumb right of center? What are the potential pitfalls?

Thanks,

Terry (OHgolfer)
