I've got a frame awaiting the same treatment (fixed, one disc) and after much trawling, I've bookmarked the Pioggia and R1.
From memory, the Pioggia is pretty much the only suitable fork if you want carbon (perhaps I ruled out others on the grounds of cost). Kinesis do a fork, but the A-C height is cyclo-X, rather than road.
I settled on R1 because they are outstanding value for money and a HY/RD can be troublesome with regards to lever throw. You do loose pad self-adjustment, but that results in a smaller, lighter caliper.
