I bought this book a couple of weeks ago. Reading the other reviews and the Camilo Villegas quote directed to the weekend golfer, I had no doubt this was a great book but I was skeptical it was also good for intermediate or advanced golfers.
I am an 8 handicap and without a doubt, this book was the biggest surprise I have had in a long time. I have played golf since I was a kid, practice regularly and had a two-plane swing. I decided to try the one-plane backswing explained by Tamayo as the proposed shoulder turn swing thought appeared very simple to perform and to repeat. In fact, it was the easiest backswing I have ever tried and the results where incredible and immediate. Not only many more of my golf shots are now hit solidly, but my accuracy and distance judgment improved dramatically. I am making at least 1 or 2 more birdies per round.
Regarding the lag chapter, I finally understood the technical reason of why making a good transition instead of coming over the top has such a huge impact on the distance attained. As I have my swing on tape, I could check that I was making a pretty good lag which explains why I have always hit the ball long. Anyhow, I learned that holding the club a little softer increased the lag I produced and I started hitting my driver around 8-12 yards longer with the same effort.
Bottom line, I HIGHLY recommend this book to all golfers of all skills that are really interested in improving. After reading many golf books, golf magazines and taking lessons for years, I truly believe this book can help your game more than anything else.
