Good responses... but the qusestion had to do with whether most pros comply with the definition of "On Plane" that says-- the club should be parallel to the baseline(planeline) or be pointing to that line with one end of the club or the other(handle or head), on the BACKSWING.

Many of David Leadbetter's students, for example, have the butt of the club pointing inside the baseline during the early phases of the BACKSWING.
