Basic Motion

[Daryl]

The difference in travel is certainly related to the amount of #3, but that isn't hinge action or motion.

Hinge action is strickly a clubface/compression concept and ONLY applies from impact to separation. It is a ball/club relationship, nothing to do with the body or anything else at its root.

Line of Compression? Doesn't it depend on both clubface rotation and path?

It depends on force vectors, so yes the path is part of the equation, but only as related to the plane/plane line. The ball doesn't care about #3 angle per se. Your feel as a player may, but the ball doesn't care.

Perhaps this conversation can be moved to its own thread, as we are on a bit of a tangent from the original post.
