If they really are THAT good in crosswinds, then I'd be willing to give them a try one day. I always assumed that even the difference in crosswind stability wouldn't be noticeable and it was just part of their marketing story. If they are truly noticeable to where they make the difference between your bike feeling like a sail and staying in a straight line then they might be worth the cost in the end. I don't know about you guys but that's the one thing I hate with high-profile carbon rims. It would be nice to have my cake and eat it too.
