I've not read the whole thread, but a LOT of touring bands (SO many) that did massive "world tours" that involved global/continental travel, opted for the Fractal gear (usually using 3, 2 mains, 1 backup) in their stage kit as it was a all about gear and shipping and "cartage". Travel had become so ridiculously expensive, and backline is always backline, so it was a matter of blowing massive dollars on hardware from stage to stage, country to country - or - doing the best they could with the Fractal units, and putting their stage together for the visuals.
I know a number of bands (Deftones, for example) where Steph uses a Fractal unit both in the studio and out, but he still relies on all manner of tube heads for finding his tone "in house". Shipping is costly, tedious, and a MASSIVE production (I remember getting a glimpse into the Stones "Steel Wheel" tour as well as "MLOR" Floyd, insane - they had 2 identical stages and ALL the gear - leap-frogging from one event to the next - so that when they were playing in A, their new gig was already getting set up in B. And that was way back in the 90s when shit wasn't nearly as expensive to haul.
I see the merits of DI to FOH, IEMs, same sound every night - no worries about failures - and saving tremendously on not needing trailer upon trailer of gear on top of whatever stage-set is designed. Cartage - it matters.
