Agree with Walter. If you don't need it, why bother with the hassle. I dive with a necklaced alternate and a standard length hose on my primary.Walter:Why a 7 ft hose? Do you make penetrations in which you have to go single file? A 7 ft hose is great in those situations, but in other situations, there's absolutely no need for it.
Only advantage I see to a long hose wrapped around the diver over the standard length hose in open water is the loop which floats out there like a big halo is eliminated. I was on a hang once when the line got bunched up with divers. The guy above me somehow got his cylinder slipped between the regulator hose and my head. Not a big deal, but I will be trying a 40" hose with a swivle under my right arm. (Yeah yeah OMG a swivel)
