The Golf Club's Longitudinal Center of Gravity is the Sweetspot (2-F). In other words, it is the Club's center of gravity when the Club is held lengthwise. It is neither the 'string' (the Left Arm and Clubshaft to which the Sweetspot is attached) nor the plane of motion (upon which the Sweeptspot orbits).

Thanks for the clarification...
