Still don't see where HK explained the need to alter setup based on the low point and true path. Nor do I see where it is explained about higher lofts creating less angle to the spin axis.

I think Lynn is right though that HK probably would have embraced the D-Plane. He just didn't think of it at the time and it seems he accounted for the fact that there would be more technology and more interpretations that make for clearer descriptions.

Low Point is not defined by the Distance between the Clubhead and Left Shoulder or any other part of your Body. If that were the case, then Low Point would be at Full Extension when Both Arms are straight and the Left Wrist is fully Uncocked. For an On-Plane Swing and Level Left Wrist at Impact, without Bobbing or Swaying, the Point at which the Clubhead begins leaving the ground will always be about opposite your Left Shoulder. Hence - "Low Point".

Higher lofted clubs produce less side spin because the Downward line of compression is greater than the sideways line of Compression. Read 2-A.

What would Homer think about the "D-Plane". In "Public" he would have said "oh, that silly thing". Then in "Private", he would have laughed his ass off. I give him credit for having an honest sense of humor.
