Everything I know about creating forward shaft lean comes from COFF. If that did'nt answer the question I doubt I could. Use the towel drill in the video, from top of swing, try to keep head steady while you try to get your hands over your left foot before impact. Hard not to lean that shaft forward that way. If that does not work, really close the clubface at address and try to hit the ball straight. This is a good way to get the Lee Trevino look, if you don't lean the shaft forward the ball goes dead left. I am guessing Brian asked about Never Slice Again, because if your clubface is open, forward lean will not help you at all. One thing that really helped me with forward shaft lean was a Hogan quote to Ben Crenshaw about hitting it low. He told him he tries to hit it on the second groove. This is what it feels like to use the tour striker to me. Thinking of the clubface at impact may set that shaft lean forward without worrying about it.
