Another vote here for H+Sons TB14 rims, especially the polished version. They built up easily and haven't needed any touch ups in over 5000 miles. But do note that these aren't the lightest rims at about 500gm, although that weight gain comes from double eyelets that carry spoke loads into both rim surfaces.
I've just built 650B wheels with the new Pacenti Brevet rims and they are also very nice.
I wasn't too impressed with Velocity Synergy rims that I used about ten years ago, but that's probably "old news" these days.
BTW, I chose the Synergy rims for the offset spokes in the rear, but didn't really notice much benefit from that feature. These days, no offset and thinner spokes (2.0/1.5/2.0) on the NDS gives the benefit of more balanced tension.
