Also, remember to use stranded wire, not solid. The stranded wire is much more flexible, and withstands repeated flexure much better than the solid stuff. It will probably crimp better as well.

I've actually used McMaster-Carr 7673K21 wire for heavy-duty aircraft servos (a few times stronger than the HS-322HDs we're allowed in FIRST), in an application where it might have to be re-fed many times through a blind conduit. It's probably too heavy for the intended use, but it's pretty much bulletproof. McMaster-Carr also sells some interesting silicone-insulated ribbon cables that might be useful: something like 9634T302 (24 AWG), for example.
