Having just ordered an Explorer through a friends dive shop
Looks like you just missed Halcyon's Double Down deal in April. If you bought the system with Eclipse wing and STA, for an extra $99 you got a double wing of your choice and their new ACB10 weight pockets.
I found the deal just as I was about to buy. It sealed the deal to go with the Halcyon. I spent a little more, but now I have the double wing.
The evolve and explorer are both doubles wings. On these, the elbow valve is centered, so behind your head, but this is the ideal location for dumping air effectively. It is also ideal for doubles as it won't interfer with the side mounting of the two first stages.
The eclipse is a single tank wing. As I recall (I used to own a 40# eclipse), the elbow valve is mounted off-center. This is so the elbow valve does not cause clutter between your center-mounted first-stage, and all the hoses coming off it, and the back of your head.
DSS wings have the elbow valve EVEN on its single-tank wings mounted in the center. I do not like this. But I am short, and so mounted first-stages tend to find their way easily to the back of my head, and if the elbow valve is resting in between, the situation is VERY uncomfortable. If you are taller, this over-cluttered jumble of first-stage, hoses, elbow valve will likely rest lower, hopefully in the crevice of your neck area.

About the positioning of the inflator hose, all new Halcyon Wings, include single tank are like this, I use the evolve 40, evolve 60 and eclipse, they all have the hose behind your head.
It's a matter of frowning on any configuration that is no suited for the intended application. Using a double wing for a single dive could have an impact on buoyancy (wing taco/air trapping) which could lead the injury (missing safety/deco stop, being hit by boats on surface etc). Use the right tools for the job must be the motto.
