As far I understand it Thom a hook is as a result of a face/path divergence. A closed clubface (closed to what? may clarify things) will start the ball left, but a plane line shifted to the right of the closed club face will put the hook spin on it. Face and head ain't the same thing. so if the clubface is closed to the path then there will be hook spin...however if at same time the clubface is closed to the target line...then hello pull-hook, or pull-draw. I hope this is not me splitting a follicle, but separate identities is a "biggie" for me.
