My favorite wheel is the Mavic Ksyrium SLC as mentioned before - don't own a piar but would if I had the extra cash. I do have a set of Ksyrium Equippes on my Simoncini - no matter what the naysayers say it is a strong great riding wheel at a great price. I have ridden 4 centurys on them so far and have probably 3K miles on them with no problems - got the set on ebay. My Tarmac has the Easton Orion II on it - these also seem quite good - less weight than the Equipes and a good ride but more expensive - for this bike I wanted the SLC's but could not justify them. Ebay is a good place to get wheel - I bought both sets there.
