Here is yet another way to determine hinge action at the 45degree/follow-thru/both arms straight location:
The SCORE LINES point AT the left shoulder = Horizontal Hinge Action The SCORE LINES point STRAIGHT ACROSS the plane line = Verticle Hinge Action The SCORE LINES point "In Between" these two points, but on most planes closer to the left shoulder, for Angled Hinge Action
Hadn't heard it put this way before, but it is absolutely correct. SCORE one -- no, SCORE three! -- for Brian!
Uh oh. On second thought, I don't think the 'score lines' visual check is quitecorrect. Here's why:
Correct Rhythm (6-B-3-0 and 2-G) dictates that the Club maintain its in-linecondition with the Left Arm with each of the three Hinge Actions. Onlyin this way can the Hands and Clubhead maintain the same RPM throughout theImpact Interval. Accordingly, per 2-G, the Left Arm and Clubface have theirlongest travel with Horizontal Hinging; a shorter travel with Angled Hinging;and a still shorter travel with Vertical Hinging.
At the end of the Follow-Through, therefore, the score lines of the club willpoint at the Left Shoulder Axis with Horizontal Hinging, as the 'score lines'visual check dictates. However, they will also point at the Left ShoulderAxis with Angled and Vertical Hinging as well. Since the Angled Hinging'score lines check' was not directly at the Left Shoulder, it is incorrect. The'score lines straight across' the Target Line is accurate for Vertical Hinging(as is the 'in-line with the Left Shoulder' visual check).
