[O.B.Left]

There are so many arguments you could make to counter the suggestion that Hogan's Plane Line was square to his Stance Line (to square up Face and Path to hit a straight shot via plane rotation)

-Stance Line has more to do with Pivot Motion than direction.... the feet are so far away from the shoulders. You can swing in to out off of an open stance , easily.

-With the driver his feet were closed but his knees , hips, shoulders were generally square.

-the foot lines drawn do not correspond to the arc . Not even close. The hula hoop used to describe the arc in the video is no where near as large as the actual club head orbit. Exaggerating the degrees of left or right as you forward or back along the arc. When you look at the arc of approach when scaled properly its surprisingly less curved than you'd think especially for shorter irons with steeper plane angles.

My problem again, is more with the procedure as it relates to the shorter irons than the longer clubs . I just don't see good players opening the face as much as suggested and then squaring it to the hole via plane line rotation. Ya it'd be straight , but weak too . I think. Wouldn't it?
