I have exactly the setup you're talking about, and absolutely love it. It's so light weight and the footage is fantastic. I will say though, monitor on for external raw is well worth doing. Braw works pretty well in Premiere now, and you have the added benefit of changing the angle of the screen. I have my monitor mounted on the back, so to the person being filmed, it doesn't look much bigger or more intimidating than the actual camera without the monitor. Here's a couple images with a 28mm FD lens (also a very nice combo)
