2:16 Same move in George Gankas' videos. Not saying GG came up with it first, dunno who did, but that doesn't matter. When two good instructors are espousing the same thing, they're definitely onto something.
Logan Dahlquist your Dad, in my opinion, is the finest instructor in the business. It’s known that he does not travel but I think if he traveled with the tour his name would be mentioned with the greats. His knowledge of the golf swing is second to none. Incredible instructor! So much respect for Dana.
