Grajan:You REALLY need to try the long hose configuration before dismissing it. Apart from being safer in an OOA - hopefully a rare event - it is WAY more comfortable because there is absolutely no hose drag on the regulator when you turn your head. It is much more streamlined, with no loops of hose sticking out to catch on stuff. Having your backup protected and close to your mouth is also a big plus. We made this change before even going to a back inflate and we would never go back.
I like the short secondary on a necklace, but I'm still leary about a 7ft primary around my neck. I usually secure my 3ft primary to my shoulder (able to easily get it off to share air) in such a way that I can turn my head without it pulling on my mouthpiece. Yes, that puts me pretty close to an OOA buddy, but I've been trained to grasp shoulder straps on ascent and at the surface until said buddy can orally inflate, so I'll be close anyway.
I guess I don't want a setup where I can get careless and end up snagging the end of a hose that's wrapped around my neck and cause breathing problems. I suppose it's unlikely to happen, but still... imagine going through narrow openings in a wreck and suddenly having the hose around your neck tighten up. Not my idea of a fun situation.
