What is it? How does it function in a golf swing? Is it useful for both methods of accelerating the club (hitting and swinging)?

I think this is an important topic . . . but I'm not really qualified to discuss the physics aspect because of the genetic crap shoot and all.

Bucket,

I want to apologize. I completely missed the "angular" in your question. I was so concentrated on conservation and momentum, that I answered the wrong question. I literally went off on a tangent.

Angular momentum is a bit difficult to get a handle on in the golf stroke because you have 3-dimensional motion of an assembly that can be roughly approximated by a double pendulum.
