I'm pretty sure that Henry/Eyebrows was using the MTB (black (racist!)) calipers with Shimano levers, and he said that was fine- the reason I mention this is that the MTB version are usually available for a lot less than the road ones.
Not sure if relevant but I have these for when I use the Midge bars with the BB7s.
