This has been touched upon in other threads, but I'm not finding the search function very useful this morning. My main rig has 2x 4 Ohm 212 cabinets. Just running a half stack has been enough for any of my recent gigs, but the fact remains that, should my HD350 die, my only backup is my old SVT head, which sounds pretty cool but no way am I schlepping that monster as a backup head. There are a number of decent-sounding,, inexpensive, tiny, class D heads out there, including one from EBS if I wanted to be absurdly loyal. But none that I have checked could handle dual 4 Ohm cabs. It may be that the mist pragmatic thing would be to just grab whatever is cheap and acceptable sounding, and in the case of a head crash of my full stack, cable it to the bottom cab only. But is there another option?
