I am new to this site. Help me understand. What is a "hitter" and what is a "swinger? Give me some examples of pro's and what type they are. Hogan? Tiger? Els? Watson? etc.

Generally speaking:
Swingers use their right shoulder in the downswing to act as a flywheel that spins and throws the club out with centrifugal force, a transferring momentum and a whirling of the club. The Swinger drags the grip end down plane, similar to pulling a rope. The Swinger’s right arm is somewhat passive, unless you are using the Right Arm to Swing (where the right elbow becomes the center of the motion rather then the left shoulder).
Swingers use a quick start down and just maintain the constant motion of Centrifugal force thru impact. “Once started, just stay ahead of it”.

Hitters, on the other hand, use the right arm to actively drive out the club and left arm, using the right shoulder as a backstop or launching pad. The right arm muscular thrust and active right elbow drives and pushes the club like an ax handle.
Hitters need to use a slow start down, but the feeling is that the club is always accelerating and driving thru the ball.

Both are extremely effective procedures. However, mixing the two, trying to do both at the same time is not recommended (some may disagree with me on this one). Centrifugal force, which is a constant force, does not like to be disrupted by ever increasing muscular thrust of hitting (vice-versa). You can pull or push. Pick one or the other, not both.

The Geometry looks similar for both, but the Physics (Pulling, Pushing) feels completely different. If you have a copy of TGM reference 6-H-0.
