Todd Graves created the Feeling of Greatness Training Club for one main reason - no matter what he tried, he could NOT match Moe Norman's lead hand grip position. Even though he practiced like a maniac, he was not able to take the correct lead hand grip "to the course".
Todd even took the extreme measure of installing putter grips on all his clubs during a qualifier (which he disqualified himself from) just so he could feel the proper lead hand position!
"As a Single Plane Golfer, I firmly believe the Feeling of Greatness Training Club is a vital tool to help you perfect the Foundation of your Single Plane Swing." - Todd Graves
In complete honesty and full disclosure, Todd developed the Feeling of Greatness Training Club for himself. Having made the decision to model, or copy Moe's swing exactly, he developed the Training Club to ensure that every single time he practiced, that he was doing exactly what Moe did in his Foundation - the Address and Grip.
