I'd say you had the rig for the job, minus the McCarty, although it sounds like you made it through just fine! I'd have done something very similar - probably my 2 Channel Custom 50, S2 Studio, and either 594 or Mira Soapbar.
The PRS 2 channel platform (C, H, Custom) makes for a fantastic gigging amp. The circuit of the amp seems more open and vintage style, in that it's more reactive to pretty much everything in the signal chain compared to a modern and more heavily filtered amp sound. It can be hard to control at first, but great once the choice of guitars, boost pedal, tubes, speaker are all settled.
I've settled on an open back PRS 2x12 with Celestion Ruby and Cream alnico speakers, and wow, does it sound great. Although, again, still very sensitive, it does best with hog neck/bodies, Humbuckers and P90's, much more so than Fender type guitars. Big bottom end, but leaner in the low mid, which is great for classic PRS builds. I also just got done moving a few preamp tubes around in it this morning, just finding the best balance on tubes that suit both channels best.
I'm really hoping that PRS comes out with an update to the 2 Channel C/H/Custom at some point. The Archon is kind of close, but hard to dial out the aggression on the lead channel, and darker sounding, too. I'd prefer something Maryland made, mainly for the sake of build quality and serviceability. The current Maryland amp offerings, while excellent in the DG30 and HDRX, is a narrow focus in the world of amps. I've come very close to getting the HDRX that my dealer has in their warehouse, but I'm just not going to drag an attenuator to gigs.
