I purchased an Easton wheelset this spring EC90 SL up front and the EC90 aero in the rear, and have put almost 3000 miles on them. So far they have been absolutely flawless. They are fast on the flats and stiff on the climbs. I have been most impressed with how these wheels handle in crosswinds. I previously was riding on a pair of ENVE 45's which were dicey on windy days. Now I can descend with variable winds and not worry about it.
As for the heating problem everyone complains about, that is an issue with every carbon clincher. If you don't want to worry about it ride tubular or aluminum wheels.
