That youtube is SCAM! Todd Graves is telling lies to promote himself.
Jack Kuykendall started Natural Golf with a Patented swing that he developed. Someone told him it looked like Moe Norman's swing, and Jack said "What's a Moe Norman". They met and Jack was able to give the scientific reason Moe had a great swing. Moe had nothing to do with the developement of Natural Golf or the name Single Axis. That was all Jack. Jack and Moe became good friends. Todd came around later after his try of the PGA failed and he hooked up with Moe to learn his swing. The Natural Golf Company was legally stolen from Jack by clever investers, they changed the swing, went bankrupt and sold the Company to the present owners. Jack went on, developed Lever Power Golf Swing, and has a new Patent pending swing, that is by far the easiest swing to learn. He discovered it this year by accident. Jack is a scientist, and was one of Golf Magazines top 100 golf instuctors 5 years in a row, he is considered the number one scientific instructor. You can check him out at kuykendallgolf.com. I went from 23 to 9 index in 3 years. I don't have time to practice all the time. His swing works for all. No distance loss. Increased accuracy, and you never need lessons if you follow his advice.
