I'm carrying the PortaBrace bags. AR-7 for my 744 and RM-Multi Deluxe for my V3, LiOn batteries, 4023's, clamp, donut and NOLAbar. Have a Sonicase, Lowepro Magnum and Nova 5 collecting dust.
Lean and mean.
Agreed, I'm lean with my AR-7/RM-Multi (standard, not deluxe) combo, but I have an AO-1X when I need space for a pre-amp or something like that. A 1.5X or 2X should hold all of the stuff you listed easily. In just the RM-Multi, I can fit; 2 tekkeon batteries, caps, bodies, 3m active cables, 2' interconnects, shockmount, small kwon-style bar, clamp, rapid adaptor, my ear plug case, a 3.5mm patch cable, and the SD7XX c-link cable. If I add the AR-7, I house my 722, the bottom lion battery, a 6' SPDIF cable + 3 BNC adaptors, a couple granola bars for setbreak. It just requires that I pack it a very specific way to get all that junk in...
I heart Portabrace.
