My Synergy rear non-oc was the same, I've got cracking around 5 of the eyelets and even though the rim runs perfectly straight and true and seems in no danger of immanent failure, I just couldn't stand the noise anymore. I was riding a 102K permanent through some very exclusive neighborhoods on Sunday afternoon and it seemed like people in their yards noticed I was coming by the creaking noises that accompanied me. Embarrasing.
I just had another 650b wheel built for a different bike that I've now put on my Rivendell so I can ride it without the noise. I was still waiting on the front hub for the other bike anyway so it's ok for now. Trying to decide what to replace it with - obviously not another Synergy. Not sure if I will use the same hub, it's 32h and I am 260 lbs or so. There are some 650b Dyads floating around in 32 and 36h. Velocity also makes the Atlas in polished silver in 32 and 36h. And Pacenti now makes the SL23 in silver, so that might be an option. It's got more of an aero profile though which I think is a bit ugly. That being said the DeepV has always worked pretty well for me and it's got a similar profile.
