Well, I broke down and bought the DVD since I really enjoyed the book. I must say that listening to Bobby Clampett and seeing him demonstrate and explain the 5 fundamentals was well worth it. Parts of the book I couldn't fully appreciate from reading and imagining are cystal clear with the video, such as load and lag. Clampett not only demonstrates but he also shares some secrets of the swing that are worth the price of admission themselves. He really takes the time to explain how the body should move throughout the golf swing. Like many, golfers I suffered from an over the top move that produced a wicked slice or huge tail on the end of my shots. After reading the book, I improved. After watching the video, I've cured it. Now that I understand load, lag and body pivot and how they work together and what it looks like and should feel like, I'm feeling really good about my game and look forward to playing more. Now when I watch the pros I can clearly see the same moves in their swings that Clampett teaches in the video. The only part of the Sybervision system I'm not quite sure about yet is the muscle memory you get from watching the specially designed series of shots. The claim is that watching the video swings is akin to hours of perfect practice and builds muscle memory in your brain. That's a big claim. But with the improvement I'm experiencing, maybe that's working too. As for the price, I found it on Ebay. I had to keep checking back because there aren't many posted there. Good Luck and Hit'em Straight.
