I actually had a marshall cab I was running 2 greenbacks and 2 v30's in. I has putting a tremoverb through it at the time. Very round and full sounding, but the speakers broke up way too early for my liking. Sounded great at lower volumes, but once it was up at band level things got a little hairy. I ended up pulling the greenbacks and running all v30's - took out a little warmth but gave it more the thump I was after.
I'll probably get dinged for saying this, but my favorite cab for the tremoverb was a stock marshall with g12t-75s. (I've never used a recto cab so I don't have that to compare too) Maybe the extra bass response in an oversize cab would give the greenback/v30 combo a little more thump than the smaller cabs have? Might be worth a try!
Alas the tremoverb is long gone...tried to quench the thirst with a 3-channel recto for a while, but just didn't do it. End random ramble..my specialty.
