Sounds sweet. I'd really like a set of deep carbon clinchers as well but I'm going to wait until I can spring for a Quarq Cinco. I don't think I can live without looking at my power data (not that it's very impressive). Psimet is definitely on my short list.
Definitely post with your impressions of the carbon clinchers once you've had a chance to get out on them a few times. Compare them to some others in your wheel repertoire. Any idea on the predicted weight for a build like that?
