I know all grips are different... but,

...assuming an anatomically average, strong grip, should the grooves in the clubface be basically parallel with the back of your left hand?

As I've become more focused on my hands and hinge actions I've found I have to align the club this way - otherwise I hit hooks.

It certainly makes sense given TGM method of using the back of the left hand, but I'm still a bit unsure about it.
