Hi,
Couldn't agree with leaguegolf more, I had a lesson a couple of months ago where the main thing he showed me was that my grip was a problem. He showed me the correct style for me, it still feels "not quite right" and I still have to guard against slipping back to the previous, more "comfortable", grip, you can always tell when I forget, the ball goes heading off into the trees on the right

.
Cheers,
Jim
