I even crimped the little lead cable stops onto the end of the brake cables. My LBS says unfarkling that rear nut is easy, and I do already have a replacement part. In the meantime they're set up right and working perfectly.

How do they work? No they don't stop as good as the Ultegra brakes. But they work fine. They look way cool and they're light. Stopping. Please. I'm worried about going, not stopping. They're bicycle brake calipers. They all suck, it's just a matter of degree. You can't stop on a bicycle anyway. Ride a 500+ lb. motorcycle, experience how ACTUAL brakes perform, then try to execute a 'panic' stop on a bicycle some time (I've done both plenty of times). On a bicycle it's a real panic situation as you realize that should you really need to stop suddenly from speeds over 30 mph, you're friggin DEAD. At speeds under 25 mph you don't need that much stopping mojo anyway.
