Unless you already have the Open Pros, you might like to take a look at Ambrosio Excellight (if/when mine turn up from eBay). Similar price and construction with allegedly better quality. I found out about them while googling Open Pros as wheel nerds in the States seem to recommend them as a slightly better alternative.
Better than ceramic open pro's? If so, they must be good
