The only Archetypes that are in stock are either completely anodized black (even the brake track) or polished silver. My front brake track is silver, so I would really want to replace both for aesthetic considerations. Part of me wants to do polished silver, but I'm not sure how great that would look with black hubs & spokes.
Given those things, R460 is my first choice since the published ERD are within 1mm of the Archetypes, and they're black with silver machined sidewall. I built some CX wheels with them years ago and was really impressed. Of course, the 24 hole is in stock but not the 20
