[Yoda]

As far as I can tell the book never gives a defination for the True Geometric Plane Line. 2-3-J says that the True Geometric Plane Line is the
basic Delivery Line. Is it the ball plane line or the low point plane line
the True Geometiric Plane Line? Do you trace the right forearm to the ball plane line or to the low point plane line. 2-J-3 gives some ideas between the true and equivlent plane lines. What do you think? What do you do?

Donn,

The Geometric Plane Line is the Baseline of your Inclined Plane. It is the 'gutter' on your through-the-waist 'pitched roof' Angled Plane of Rotation.

To properly Deliver the Clubhead into the Ball, the simplest procedure is to Trace this 'gutter' -- the Delivery Line -- with your Right Forearm, Bent Right Wrist and #3 Pressure Point. As you Trace this Impact Point Plane Line -- that is, point at it (with the Clubhead's Sweet Spot) through the Impact Interval -- you simultaneously are Tracing its parallel Down Plane Low Point Plane Line.

However, as an alternative, you may choose to 'cover' -- as opposed to 'point at' -- either of its two Visual Equivalents:

(1) The Curved Clubhead Blur (Arc of Approach) through Impact and Low Points; or

(2) The Straight Line Clubhead Blur (Angle of Approach) through the same two points.

As always, Homer Kelley did not dictate your choices...

He merely illuminated them.
