Seems like just speed. How can you add weight (mass) to the club when it's already moving ?

Effective mass basically is gonna vary based the size of the radius employeed . . . . so maximum radius is gonna be achieved by getting your "pivot segments" from out of line to in line from the ground up . . .




Note how all of hogan's pivot segments (joints) are "out of line" or bent . . . left ankle bent . . . left knee bent . . . hip sockets bent . . . spine flexed . . . neck down . . . but you'll see as the club gets down to it's release point Hogan quickly gets the segments "in line" by extending those joints . . . . via using the ground . . . forward and up . . . ankle . . . knee . . . hip . . . spine . . . even neck . . . (of course not to mention the joints in the power package) . . . all of these segments releasing at the proper time and rate help to keep the club on the plane angle and tracing the plane line (entire club lays on the face of the plane) . . . hogan laid it on the face of the plane better than anybody ever . . . much of it because of his pivot.

In addition to all that the head being in the proper spot and the pivot lag being maintained aids in maintaining the wedge alignments and also allows you to impart a hinge action versus an out of control swivel thru the ball.
