Hi Elan - Yes, have integrated inflator on doubles wings (and CCR wing so I can access on board diluent). With my doubles set up I have one reg with a second stage with a long hose and SS dog clip on one post and reg with a second stage and "normal" hose with a necklace on the other. Except for the modularity issue I would probably not bother with integrated inflator on doubles as there is already a spare second stage, although I guess if you were paranoid you might worry about having to supply 2 out of air divers at the same time (unlikely). Sharing gas on a long deco / swim out of overhead / in current (the dives you might be more likely to do with doubles) is significantly easier when donating a reg with a long hose, but my point was that I have found integrated octos a good alternative to a conventional octopus in some situations - especially no deco single tank diving. Just something that works for me. Another personal quirk is that I really like independent doubles ie without a manifold - for a number of reasons, but particularly because I do a lot of solo diving and diving in places were manifolds are hard to come by.

Ok I see now. So you basically have 3 second stages.
