Great! The first time I read through it, I didn't think much of it... mostly because they seem very wedded to their particular system. I shoot a variety of methods, depending upon the target, and thought that I'd have to be using their system to get much benefit.
However, after a closer second read, I pulled some specific tips and tried incorporating them into my shooting. I've been mostly hunting for a couple months now, but a little before our winter sporting clays league starts up, my wife and I are going to spend some time practicing the flashlights drills they outline in the book.
