Yeah... they're not precisely the same rim except for different labels. What I mean is that the dimensions, weights, and extrusions appear very similar among those three, but the CR-18's are about $30 while the NoBS and the Weymouth are nearly $60 each. Since I build my own wheels (I have for 33 years), the extra cost of the rim is significant. What am I missing?

I want to move forward, but I've had a run of bad luck with wheels lately. A pair of Velo Orange Raid rims were nice at first, but they started making a noise that I believe was loose eyelets. I couldn't make this go away after rebuilding and retensioning them repeatedly, so I exchanged them for Velocity Synergy rims. (Universal Cycles worked with me to get this done.) One of the Synergy rims is now hanging in the garage with splits at the spoke holes. Grrr...
