John, Some sheet wrapped graphite shafts do have a "spine" that "moves" as the tip is trimmed. This is NOT a common occurrence. A much more typical spine in graphite (and certainly in steel) is a straight spine.
I'm a little curious about his "inefficient" comment. It seems to imply that he doesn't dispute the existence of spines and that (perhaps) he has an "efficient" way to find them. Once he found one I wonder what he does with it?
It seems more likely that he doesn't know what to do with a "spine" and he is trying to baffle you with BS and dodge the question. (Just for curiosity, he wasn't one of those guys at The College of the Desert flea market was he. If so, I'm 99% sure that his answer is BS).
Having said that, "spines" are somewhat a religious argument among clubmakers. There are a variety of orientations that various people view are "correct." I believe all will agree that whatever orientation you use, make sure it is consistent within the set.

I was told last week by a club fitter in Palm Desert that spine finders are inefficient because the spine wraps around the shaft. I got a sense that he was saying spines are shaped like a corkscrew. Any comments?
