QV, We're in similar boats.

I can swap the lighter wheel set and tires from my crit bike to make the CAAD3 lighter,
maybe sub 9.0 kg, but I don't see any reason to make the crit bike heavier. Still it's nice to have a compatible wheel set available if needed. I also have an older Cannondale project that I'm gathering parts for that and I expect it to be in the 10ish kg range.
The 200 really came out nice and I just noticed that the nipples match the frame.
