Of the three, Zeagle also makes a great backplate. I haven't dove one yet (I use a Deep Sea Supply rig) but you can pick one up on ScubaToys.com, I am sure.

I'm not aware of any BCs that are weight integrated and can carry doubles (at least backmounted). The closest would probably be the Dive Rite Transpac.
If you truly want something capable of handling double tanks, get a BP/W. You'll just end up there when the time comes anyway.
By the way, why does it need to be easily adjustable? Will other people be using it regularly?

Walter you forgot that if the OP uses any of the above mentioned BC's that they would kill themself. That drag is going to just kill the SAC rate it might go from 6 to 6.1 thus causing them to reduce their dive time from 20 minutes to 19.5 minutes. Give me a stinking break. If drag was a big issue the cave divers would have another system instead of the long hose. Remember there is extra hose causing extra drag
A lot of people use the Ranger for doubles. I didn't do it but I do use the Ranger bladder on a plate. For what it is worth I converted three DB's to a Zeagle product from Oceanic.
You are mistaken. None of those BCs will kill a diver. Lack of skills (all to common) and stupid mistakes (something to which we can all fall victim) can kill divers.
Hey, if you like a rig with lots of drag in a ripping current, it won't bother me, go ahead and use one. As far as the long hose, I think it is used in many situations in which it is not necessary, but in any penetrations where divers must proceed in single file or go long distances to the exit, they are essential. Also, a long hose does not create all that much drag, especially when compared to a poorly designed BC.
Whever I get tangled in a net I just motion my buddy to come over and cut me out. But I can't even remember the last time that happened, if ever. I would be much more worried about losing a belt. And some divers can't wear a heavily laden belt without that risk being very real. Your info on new belt technology is valuable, though....think about being tangled in a net, having to remove your rig to untangle yourself, losing your grip on your rig and making a buoyant ascent into the net which is billowing over you, youre dead.
The Zeagle Ranger can easily handle doubles
give me a break.
