PLANE ANGLE/ SPINE ANGLE?
 

How many of you believe that the Spine Angle at Set up (down the line) actually somewhat dictates the STEEPNESS or FLATNESS of the Plane Angle one will swing on, or... is this determined more by flexibility, concept, or other factors?

This seems as if it should be a factor here (Spine Angle at Set up). However, if one looks at Hogan and Toms, for example... they look to have very similar spine tilts at Set up, but swing on much different Plane Angles.

True, they have similar positions at address, but IMO Hogan 'did less' to get to the top. Toms must 'direct' his hands, where Hogan just 'let them swing'.
