You're on the right track with Open Pros. I built my Campy set with C2 Belgiums and Record hubs, and will probably swap out to Open Pros (the hard anodized kind) this Fall. The eyelets make it easier to get them round and true (in my opinion). Also, yes, Campy 11 works with the hubs.

Word to the wise though, watch the hubs out of the box. Both of mine needed tightening after the first ride. It's easy to do, but still something to be aware of.
