My metal version had the same construction difference as yours, I believe. The action often baffled me. Sometimes I thought it was a little too high; sometimes there was that "detuned two steps and now things feel a little floppy" kind of vibe going on. Again - after crossing the vintage threshold, those few problems didn't seem to be much of an issue anymore.
Ah, good to know. This one's been pretty stable. Not roadworn yet, hence the puzzling action. At this point, maybe the wood just needs to breathe...
