Turns out that I'm starting to find my Ksyriums a little harsh on my new Orca. I had Ksyriums on my old Trek carbon and it was never really an issue. So I was wondering what kind of wheelsets some of you have tried and find work well with the Orca. I'm looking for something stiff and light without the harshness. I'm kinda eye the Easton EC90 SL carbon clinchers but my current hang ups are on long term durability and failure.
