Each of the five Swing Thoughts expressed in the poll were either direct quotes from Homer Kelley or a reasonable facsimile thereof. You couldn't go wrong keeping any one of them in mind during the Stroke. Nevertheless, when asked to identify the most important thing to keep in mind during the swing, he responded without hesitation.
And his answer was...
<drum roll please!>
Number Four: "The Right Forearm tracing down the Delivery Line."
Homer described the Inclined Plane as "the heart and soul" of the golf Stroke. And Tracing the Delivery Line assures staying On Plane. The Delivery Line could be either the true Geometric Plane Line (Swinging) -- the straight line baseline of the Inclined Plane; or, the Angle of Approach (Hitting) -- the geometric equivalent of the Arc of Approach (2-J-3).
He added that the thought might be peculiar to him: He had spent so many years focusing on getting correctly to the Top that he needed a key to get him from the Top through Impact!
Congratulations to the nine percent of the voters who got it right. Now, let's all get out there and Trace!
