Dear collective wisdom,

I ride a Specialized Tarmac with Fulcrum 6 wheels. I'm now looking to upgrade my wheelset. I ride about 200 miles a week, at a pretty good pace. The terrain here (New England) is rolling/hilly. I'm hoping to start doing some racing. Basically, I'm looking to spend around $1,200. I've been eyeing the Mavic Cosmic Carbone SL. Thoughts? I've also read some good things about the Ksyrium SL wheels (and, even the Ksyrium Elite, which are much less expensive). Thoughts? Is there something else out there I should be looking at?

Thanks!
