Eminence wamp thang or Celestion redback or...

I play stoner metal and doom in a 5 piece band with another guitarist. My signal chain is a green russian muff and a rat into matamp gt120 preamp clone, all powered by a harley benton gpa 400 going stereo into a 2x12 with two v30s. For now I would like to ditch the v30s. But in the future I'm probably going to add another 2x12 cab to use the v30s (or other speakers) with the one I'm choosing now.

For now tho, I need two identical speakers (since im doing a stereo setup) to use in a single 2x12, and I was thinking about the swamp thang or the redback.

Which ones would you recommend? Are there any other alternatives that I haven't taken into account?Has anyone tried both or has tried one of them?
