I have done SM dives with 2 stages & 1 deco gas. It was hard to push new cave with this much junk on. Mostly there are a lot of faffing around and you barely get much more time/gas than bringing giant lp120 sized SM tanks (which I have never had) and a single stage. It works, but you are rapidly getting to the point of diminishing returns.I'm not sure it is a good idea in a cave either.
