Im also considering a set of Zipp carbon wheels but the math doesn't work for me. My current set, Bontrager Paradigm Comps, weigh in ~1600 grams or 200 grams more than a nice set of carbon wheels, not a lot of savings for the cash. Have you looked at HEDs? I have a sweet set of Ardennes on my gravel bike and the new Emporias are nice also..
