The problem with carbon clinchers lies in heat transmission and retention. The beauty of an aluminum rimmed clincher lies with aluminum's inherent heat dissipation properties. Aluminum doesn't retain heat very well. Put an aluminum pan on a stove, heat it up, turn off the heat and the pan cools down quickly. That's why professional cooks use stainless (better heat maintenance). Although aluminum's heat retention is bad for cooking, it's great for cycling.
Carbon is more like steel in that sense: carbon will retain heat far longer than aluminum. As the carbon heats up and doesn't dissipate it very quickly, the resin which bonds the material together can breakdown. Also, the more heat that's built up, the less effective your brakes are. That's why if you are riding in flat areas, where the stops are relatively short, the wheel doesn't have time time to build up heat. Personally, I've even ridden in some mild hilly areas (Central Texas), and haven't had a worry about the build up. That being said, I do keep a set of aluminum clinchers, given my weight and size, for use in really hilly rides. However, 99% of the time, I'm on my CF clinchers (formerly Reynolds DV3K's, now Zipp 303's).
Is there a benefit to a carbon clincher? Absolutely. Asthetics aside, carbon clinchers are generally lighter than their aluminum brethren (when comparing equal size wheels). Aluminum, although light, is not strong. Pound for pound, CF is stronger than aluminum (and steel, for that matter). To match the strength needed to make a wheel, builders have to resort to a couple of different options: either use more material (weight) or exotic alloys (cost).
Personally, I have never tried Mavic wheels. Some love them, some hate them. I'm indifferent. I can, however, tell you two things: first, there seems to be an issue mounting tubeless tires to them (see my comment below on tubeless). Second - and this has nothing specific to Mavic - I recently switched over to the wider rim width, and I will never go back. The wider contact patch is noticeable, and provides a more stable footing. Also, the tires seem to absorb a little more impact than my old narrow wheels. Since Mavic hasn't embraced the wider rim mantra, they're off the table for me (for the moment).
Now, if blowouts are your primary concern, I offer an alternative to you: tubeless tires. Almost any clincher wheel can be converted (using tubeless specific tires - standard road clinchers are NOT recommended for the conversion, due to tire pressures), and the very nature of the tire's locking bead is to prevent the tire from ever coming off the rim. Personally, I need two tire levers to make the initial removal of the tire off the rim. Yes, they are more complicated to setup than a standard clincher, however, when on the road, if you do suffer a flat (as everyone from a clincher to a tubular will tell you, does happen), you can treat the tire like a clincher and just put a tube in the wheel and ride on. Is it messier than a clincher? Yes - there is usually sealant in the tire, that prevents/seals smaller leaks - however, you eliminate the tube (weight savings), have a lower tire pressure (more comfort), eliminate the risk of pinch flats, and have minimal downtime during a flat, compared to swapping out a tubular tire.
