Zeagle works well for the type of diving I am doing now but they dont seem to be very popular with other tech divers I have spoken to. QUOTE]
Must be the water.
I'm mulling over the same question; I have two Zeagle second stages and three Zeagle first stages. I've mocked up a set of doubles (bands-no-manifold-I'd-like-to-use-up-the-Nitrox-first) and have briefly fiddled with the hose routing using an Halcyon Evolve 40. So far, I like the routing of the "cross-over" hoses (for lack of a better description) behind the wing from the rear LP ports with everything else in front of the wing. I don't like the bends in those two hoses and am considering Myflex type hoses for the backup and inflator..........OR......... two HOG first stages to go with the two second stages I recently bought (with ten dollar rebuild kits). I'd also like to see pictures of doubles hose-routing with Zeagle regulators.
