As mentioned, do contact RH, a phone call would be more helpful as it's a two way conversation real-time where emails are like sending a letter to outer space and waiting for a return, like when you get one of those spinning wheels from a website. Waiting forever.
Otherwise, count me in the with a basic Dia-Compe style carrier for being reliable and very functional. I don't see the point of the roller types or any that you can't readliy and easily remove the cable from. To me they are limiting, you can't simply unhook and completely remove the cable to fully open/release the brakes. Even the Tektro carrier that encases the cable is worthless in that regard. These are cases of over-engineering something that isn't complicated, in my opinion.
