Hi, UK!
I'd shoot Jefro's scenario a bit differently for his two Nevada Sweeps starting from the left, although whichever way works best for you is the way to go. When shooting left to right I always fire my left pistol first. In his scenario I'd shoot L1, R2, R3, L2, L1, R1, L2, R3, R2, L1. It may sound a mite confusing but in minimizes arm movement. In any case, shooting gunfighter is a whole lot of fun. I originally shot double duelist (left pistol left hand, right pistol right hand) but got converted by a couple of gunfighters in my club and have never looked back.
