Sorry, I can't really answer your question, but I'm also very interested in this wheelset and would like to hear some feedback as well. I know that the previous Rolf wheels such a the Vectors etc., were very, very good wheels and so I have no reason to believe that these aren't the same quality. The only downside I can see is that you may not be to rationalize a super sexy pair of ultra light carbon wheels if you own the vigors.
