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.
