Looking at getting a twinset, already have basic hardware. Does anyone know where i can find a manifold with only one port for first stage. i have been informed that some older models do but haven't found any for grabs. Anything else i should consider before my switch besides bc ect ?

There are no modern single outlet manifolds made.

The more salient question is why do you want doubles if you arent using 2 two regulators for redundancy? Just get a big single, like an HP130. Its lighter, cheaper, and fills are less (unless your shop fills by the CF)

ya but what if i need twin 80s or 100s. Just saying i stumbled upon some hardware and i'm interested
 
Regardless of whether or not there are manifolds currently made for doubles with a single valve, I would ask again, why? Doubles with a single reg valve is justing carrying around stupid amount of weight with no real benefit. As @rjack321 pointed out, things would be easier with a big single tank.
 
There used to be solid bar manifolds to sell, SOME military and professional organizations still use them, and, i guess that you still May found them in europe, maybe asia, and they appears at aqualung japan site
But i don't see why not having a dual outlet for redundancy, and if the point is Just gas volume, a bigger steel tank would be ok.
 
Divers who dive double-hose regulators often prefer a single-outlet, solid bar manifold for their doubles. This type of manifold locates the DH "can" correctly (i.e., lower, between the shoulder blades, and closer to one's back). A large single tank will not allow this.

Moreover, many people find that doubles "balance" better than a large single.

My double lp50's trim and balance better than a single 100.

Yes, I own an OMS (Faber) LP 126. It's a very long tank and has an 8" OD.

I also own a pair of OMS (Faber) LP 46's and the hardware (including a two-outlet OMS manifold) to dive them as doubles. The little doubles balance much nicer (for me) than the 126. They are a bit short for me, though. Probably, LP 50's would work better. And, with a custom single-outlet, solid bar manifold, they (the 46's or the 50's) would probably make excellent doubles to use with my DA Aqua Master that's been improved by Vintage Double Hose.
