What cabs are you using now then, Alan?
Two identical Laney 2x12's (GS212ie), both now fully loaded with greenbacks. My vintage Marshall 4x12 has now gone.
I had a "magic" event when my rig just sounded so perfect, playing through one of the Laney cabs. It just didn't sound as good through the Marshall, so I sold the Marshall, and put together another identical Laney cab with greenbacks. Two greenbacks on their own is just not quite in the safety zone for me for gigging. Four is fine though. The two 2x12 cabs gives me a pretty flexible setup too. The gig I did on saturday, I set them up on top of each other, end on end, to have a really thin but tall stack .... didn't take up much space but got plenty of sound up around my lugholes.
