[O.B.Left]

Daryl's drawing wasn't focused on the inclined plane, but the drawing is still relevent to it. The bottom edge of the triangle (clubshaft) is lying on the inclined plane from release to follow-though. The other lines are not related to the inclined plane, but are related to the plane of the left wristcock motion.

He could make it fancier to show the inclined plane/sweetspot plane, but I'm pretty happy with the artwork.

Bagger nice to have you posting again. Are you saying that the left wrists direction of cocking is aligned towards the left shoulder despite the Inclined Plane Angle? Id maintain it cocks and uncocks on the Inclined Plane whilst the left hand is turned to plane. Making D's drawings accurate for a "left shoulder" plane , only.
