As much as the FRFR solution is (imho) very much about hearing one’s instrument without the colour certain amps and cabs give to it, for me the weight and size issue was hugely important. The K12.2 rattles my house just nicely! I think you are being wise not putting all your eggs in one basket.
I looked. It reminds me of a rig I used in a thrash band I was in. There is a hugely heavy Acoustic (as in the make) head and cab at one of the venues I play at that I deeply covet, if I thought they’d sell it to me I’d buy it in a heartbeat, but, I don’t think I’d use it if I got it home, nonetheless, for some reason, I still want it.
