Late post but I use a Large Kifaru belt pouch that I had laying around, fits 40ft of Canyon 9mm with madrock and quicklink. I can barely stuff it into the medium pouch but large is easier, especially in the dark. I just picked up a Marsupial gear Molle belt which has the molle going further forward than most belts I've had in the past, making it a lot easier to get the rope back in there.
