How deep are the wrecks? Are you also taking deco bottles? All those tanks twinned are real backbreakers - LP 121s twinned and righteously pumped weigh 119 pounds which isn't too bad in a gym but on a pitching, rolling dive deck or ladder can do a number on you. It sure is nice have 320 cubic feet of gas strapped on though. But with a deco bottle or two, you are talking some serious rigging, like Andrea Doria-serious rigging.
For anything down to 210', I use twin LP 85's. Properly filled, they weigh in at 65 pounds with 230 cubic feet of gas. Way easier to manage, and I'm 6'2". Granted this is southern Florida where the water is not too cold and sometimes it's even clear.
When the HP 130s rolled out, lots of guys down here twinned them out. Fill Express looked like Costco full of these babies. And man, they were heavy. There were a lot of guys who couldn't handle them very well, even in the parking lot. Nightmares on a dive boat with a bunch of these guys - gear everywhere, tempers flaring - great fun to watch.
So if you're doing 250'-deep wrecks up there in wicked current and lousy viz, take all the gas that you can. Otherwise, you might want to consider something smaller and easier to lug around.
There is a guy down here who uses twinned LP 66's - leetle tiny baby tanks like something you'd strap on a kid. He had his own shop so he could whatever pressure he wanted in the tanks. That's a rig you can carry with one hand, but he had decades of experience honing his gear.
