You also could try something like a Mavic Cosmic Carbone or Hed Jet. The Mavic's will likely be lighter, but that will give you aluminum clinchers with carbon aero fairings.
I have a set of Cosmic Carbone SLRs. They weigh in at just over 1500 grams, and work well, but I haven't really used them since I switched to carbon tubulars. I actually have them listed on Craigslist now, so if you are interested, PM me.
