Well I got the book, and read pretty much the whole thing this morning. I have to say I liked it. It covered most of my questions and concerns. Its not really gap shooting, but its not really instinctive shooting either. Its kind of a hybrid. But it is really good for describing a particular form for shooting. I haven't been able to work out my own form, so I figured I needed to try set method. Hopefully I can settle in to this style and improve my accuracy.
I was worried that it might be a little hokey with all the comments about zen and stuff in the reviews, but it was actually quite practical and helpful to me.
