Without meaning to derail the thread (but doing it anyway), it happens in singles with the hose routed directly down from the 5th port as well as in doubles, similarly routed straight down. In both cases it's tucked beneath the light canister. It doesn't happen with a regular rubber hose. Also, I second the the thing about the snaps not staying put. I have to push mine back toward the 2nd stage periodically. If I were less lazy, I'd switch back to a rubber hose.
Ok, thanks for the clarification.
