I'm using the 5L steel tank from Drager, while waiting for my 10L H valve to arrive.

Be aware that diving a big tank doesn't let your gas outlast the scrubber duration though. One option is to decant from a 12 or 15 into the Drager tank.

The better option is to work out your vO2 and use gas/jet matching to get longer duration dives. I almost always use 40% through the 60% jet.

I have posted the formulae elsewhere on here.
