I learned a valuable lesson today. The Sweetspot Plane. I alway knew about it. I can describe it, draw it, and tell you everything you ever wanted to know about it. But today I learned that a swinger has to set up (Impact Fix, etc.,) with the Clubface open. Not just because it closes with Horizontal Hinging. When I set up with the Clubface square I couldn't Turn my Hands enough in the Backswing to get the Clubshaft and Sweetspot on the same Inclined Plane (unless-Bent-left-wrist). You have to start with an Open Clubface. The more loft, the more open. No More Shanks.
I know it's in the book. But you don't know (really know) things by reading alone. No one ever learned to hit a golf ball by just reading a book. (ya gotta see the movie)
