Like the title says, looking for some input on race wheels for the upcoming road racing season. I was planning to race my 404 FCs but after a friend overcooked his Zipps in a local race and wound up with a pretty bad injury when the tube (and wheel) exploded, I'm feeling a little less confident in them. Granted he was running latex tubes and this was a fairly technical 7mi descent but still. I race in Western PA and WV mostly so our races typically have 3000-5000' of elevation gain and an equal amount of descending, some pretty fast and technical ones at that, so I'm thinking about moving to an alum/carbon wheel for a little more piece of mind. Has anyone else heard/seen much in the way of carbon clinchers overheating in road races or is this just the result of a uncommon combination of factors?

What is out there in terms of a high quality, high performance wheel? Is the Cosmic Carbone the best bet? The Exalith braking surface seems pretty nice. What about the DA9000 C50s? Any other brands that would actually hold up to road racing? I've currently got Ksyrium SLS' and a sets of DA9000 C24s and C35s but looking for something maybe a bit deeper/more aero.
