[O.B.Left]

Steeper plane (say 60*5 iron) = less out = less plane line rotation left to zero out path and face (if the ball is not a T)Flatter plane = more out therefore more plane line rotation to zero out the path and face.

Interesting Okie. Are you assuming the clubface is square to the Arc of Approach or true path before you rotate the plane?

Here's a Trackman diagram........all looks kinda familiar except some of their terminology is even weirder than ours. Something I previously thought to be impossible. Im with Homer on this name game......"Plane Angle" is a far better handle than Vertical Swing Plane. Maybe Im missing something however.
