I looked at all of those on the Rivendell site over the past couple of days. It isn't obvious to me that the Albatross bars would be comfortable, with that near 90 degree sweep for the primary hand positions. But never having used one, what do I know? The 60'ish degree sweep for the North Road bars feels like it would be a more natural hand position.

Rivendell sells a bar with a little less sweep, the Nitto Dove bar:
