Hey Chuck, perhaps something a bit more Boeingy is called for. A few yrs. back, you were talking about oriented carbon composites for the internal rod. Is that still on the drwg. bd.? No one (including the advocates of portability) who's fiddled with this can have much objection to a lightwgt. external truss but the rigid internal rod is the Grail. Anything new doing there? Any developments not involving the physical limitations of calipers? Lasers, medical imaging process calibrated to measure? Or are we stuck in the anodized gimmick approach?
