[O.B.Left]

I may be wrong but in your original post I thought you were maintaining that Homer's view of "orthodox" putting included a vertical plane of motion, the clubhead covering the line and vertical only hinging.

If this is correct and given his own personal preference for angled why would he suggest vertical and covering the line etc as the starting place for the development of the putting pattern?

Perhaps I am confused? The great thing about this forum is that no matter how dumb the question the answer often contains some significant insight. I had for instance, never appreciated how angled hinging approaches vertical hinging as the plane angle steepens. "Mind blowing" as we used to say.
