From those wheels you mentioned, I would go with Easton. They've been in the wheel game longer than most people think, as they used to be called Velomax back in the day, and have always built fantastic wheels. Those Mavic R-Sys wheels have been recalled, and was the biggest industry news at the beginning of the year, plastic spokes=junk, unless they're Lightweights. The Mavic wheel that I really miss is the Helium, that was a great wheel.
A good thing to know about the OP would be his requirements, riding style, weight, and local road conditions.
