OK - so I'll try to clear some confusion. It's not an expensive wheelset, with standard "parallax" (Alivio level, I think) hubs. I've been pretty gentle to the wheelset, repacked the cones about 3 times so far, made sure everything was properly tightened and that the spokes were generally even in tension. I have done 1 full tour before on this wheelset, but I'm only 130lbs on a heavy day, and carry maybe 60 to 70 lbs for fully supported touring, so total weight bike+me+luggage would be ~ 230lbs. I've also done a few daytrips with ~30 lbs of gear.

The spokes have *never* given me a lick of trouble, even during/after these trips. I don't see why changing these as-yet problem-free spokes over to new rims should cause them to become more prone to breakage. So, I'll be siding with the contrarians mrrabbit and prathman. I've check my spokes, and they have "N" on the head - Chun Nuan Co. of Tiawan apparently. No surprise here though, as they came from a GT bike of the 90s....

@BikeWise1: I'll be camping for my trip, and generally low budgeting the whole thing. $1 per spoke IS whopping for me, no matter what. If spokes can't be had for less that $1-2m ea, it just galvanizes my resolve to re-use spokes. I may pick up 3 or so as spares, however.
