Hey man, I have had a few sets of open pro's w/ campy hubs and race on them as well. Good wheel for the money, being a big/strong/heavy (any of the above), I would go for the cpx33's as mentioned above. The eyelets will pull through and split the rim on the open pros rather fast. I get them built up for the rear only as the front does not die, for around $60 AU which is about $40 us, (rim, spokes & labour) so I don't really care if they don't last forever.
I am looking for an alternative to the open pro, just it is too simple for me to use them.
