Hi Chuck, another great set of pics. Your set ups are always clean, sleek and professional looking! You were right about the R12 - it's rated for 350 pounds. I can't wait to get my second SB2A and run them together with my 360's. I carry a little more lighting than you (chauvet 4 bar/4 play/6 spot and adj micro lasers on a stand. With a cord bag, speaker & light poles, my SKB dj station and misc items, it takes me 3 trips minimum to load in/out. I want to get a pr. of EV ZX1A's to lighten the load.
