In another thread [Ted] mentioned this little gem:
"Mainly, I cover the [Angle of Approach] line with the Clubhead. It forces the steepness of the Plane.
Homer was asked why it was such a good procedure and he said he didn't really know, but he thought it might be because it went so well with Steering."

For Hitters using the Angle of Approach procedure . . .
Priceless.
For all others, just go on about your business, i.e., Tracing the Straight Plane Line (the Third Imperative / 2-0-B-#3 per 7-5 and its Variations 10-5-A, D, and E).
