The Clubface does Close relative to the Plane Line.
But I said relative to the Clubhead Line of Flight.
If the plane line is the invisible line that the clubhead travels upon then wouldn't the clubhead line of flight be the same as the plane line? If you swing the clubhead inside to out then you have an inside-out plane line, if you swing it outside to in then you have an out-in plane line.
Also, if you take the clubhead up sharply you are increasing the incline plane and if you take it away flat you are decreasing the incline plane.
I think the clubhead is inseperable from the plane line.
