I'm running open pros laced to vintage Campy record pista hubs w/ double butted spokes and they're great.
This time of year there are a lot of huge pot holes in Toronto and I have hit a few pretty hard, and my wheels are still true with no flat spots.
I have heard very good things about the DT Swiss RR 1.1 rims though, apparently they're stronger than the open pros and they're similar in weight too.
