Currently riding Synergy rims, 26" 36h with a 3x build. I went with a non-OC rim for the rear, and am running a 10sp cassette. Wheel has been totally bombproof in practice. Last time I had it in the stand for service, I tossed the wheel on a truing stand and was amazed how true it remains. I'd not heard anything bad about the OC rims, just more used to dealing with symmetrical rims and didn't want to get into something new for my commuter wheel build.
