I would not race 303/zipp/expensive wheels for CX, unless money is no object or you have access to free/cheap wheels. Round here, the cross courses beat the snot out of your equipment, especially wheels.
thanks for that perspective. zipps have, for me, been bomber on the road (& dirt road/gravel/washboard), but i don't know the rigors of CX like you guys do, so i'm grateful for the input. what is it that beats them up so bad? are you worried about rims, spokes, or hubs...or all of the above?
i'm on the lighter side (150#) if that matters.
that mech to hydro converter looks messy, fragile & heavy.
