I normally use a 7-ft hose, but there is one specific situation for which I have been thinking of getting a second reg set with a "streamlined" configuration (where the hose, say 5 ft or less, is routed under my arm and through a swivel or elbow by my head). The situation is when diving from a Zodiac/RIB or panga, where the crew is helping me and other divers with gear. They just don't seem to know how to keep the hose tidy, and it gets wrapped around things or becomes a tripping hazard when the crew member attempts to stow my rig for me as I am climbing back into the boat, and once aboard it may not be within close enough reach that I can clean it up. Basically, we're talking liveaboards and resorts. I'm just tired of having to deal with the 7-ft hose because the crew doesn't know how to handle it.
