Pair this with John Hoskison's other book "A golf swing you can trust" and you have two superb books on the swing, and how to go about REALLY using it effectively. There are so many books that get bogged down in detail, drills etc and miss the fundamentals - low scoring is how you think your way around the golf course! Read this and use some of John's insight and you're on the right track to bring those scores down!
