I commute in NYC on my Carlton, which is equipped with vintage campy hubs laced to Ambrosio Evolutions. I have about 500 miles on them. They look great, feel great, seem durable so far - bear in mind this is daily commuting on the streets of Brooklyn and Manhattan - and in my mind having Ambrosio clinchers seems to mitigate the fact that they're not tubulars. I haven't had them go out of true in the slightest.

Then again, they were built by a top-notch wheelbuilder who's probably built thousands of wheels. When I brought them in he said, "these are really nice rims." That was enough for me.
