I can't tell you what method or putter Homer Kelley used when he played with Bruce, Jay and Don.
I do know that Homer Kelley would have liked the fact that your friend had a stroke that put "immediate" over spin on the ball 2-C-4, reducing or eliminating skid.
I do know that Mr. Kelley had three different putters to work with different stroke types. Specifically, the reverse lofted putter is only needed for a "true swinging" putting motion in that the face is only square at low point (at least for a straight faced putter) and that the reverse loft is therefore needed if you wanted to hit the ball above the equator at low point - in order to give the ball overspin and start it rolling right away. Since he didn't tend to putt using a true swinging procedure- I'd guess that he wasn't using a reverse loft putter for that round of golf.
Hopefully DG or Bucket will now threadjack this thread - because the power just went out and I need to head down to the freezer and check on some of my prized possesions - they don't do well when they thaw - I'll double check to make sure that my "Bucket" shelf is still empty.
However, as always - it's not so much what putting procedure you are using but rather the importance of understanding one's putting procedure in order to repeat it and correct it when necessary.
Man . . . I thought you were quitting at 1000 posts . . . . did the hair on your palms get stuck in the key board or something?
