Bucket have you tried "ABG", Ass Back Golf? Im reluctant to give the name of my future book away but there you have it. The lever extension coming more from the left knee than the spine angle as a drill or a feel to help steady the left shoulder in 3D space.
Yep . . . that's what I'm working on now . . . it's gotten lots better with the irons . . .driver still a struggle.
Are you sure that Mike O doesn't have a copy right on that name?
