I'm building a new wheelset on some ultegra hubs I picked up. I'm looking at Mavic Open Pro - just because I seem to see this one written about everywhere. I've only built one previous wheelset, so I'm not planning anything special or very unique. Nonetheless, these will by my wheels so I'd like to put something together a little less ubiquitous than the ultegra/open-pro combo- but I know very little about rim manufacturers and their models. Any suggestions/recommendations for comparable (in quality and specs) rims from other manufacturers?
