The amp that I just bought - Randall RH200 G2 - mated to a Behringer BG412F - 412 cabinet + I'll have it hooked to one of my Ampeg 412 cabs during live play, it's at the rehearsal studio.
Picture of my rack setup that I use as well, through my 2 Ampeg 412 cabs
I was actually thinking about having these two set up on a an A/B pedal so that I can have a lot more variation with my cleans and dirty sounds. I could set up the rack unit for my cleans and then the Randall for some dirty stuff.
I am sure some of you guys do it that way, right?
