Hm, Combo will be pretty much the same, except for the speakers. Keeping in mind that 50% of the tone you heard cam from a DI box, the difference will be minimal.
I like 2x12 cabs, they are more complex than 1x12 but you don't have to crank to insanity to have the speakers move air.
The one I used here was a closed Heritage with reflex openings and one V30 (this is in the Combo) and one G12H30.
