The RB is a handful. I haven't tried the left hand grip yet but I think a Bronica GS-1 with a Speed Grip is easier to hand hold. When I want to use a medium format camera which isn't too heavy I take a Bronica SQ-A with a Waist Level finder, back and 80/2.8 lens. It's a lot lighter than the RB and I don't mind the laterally reversed image. Even with a prism finder and Speed Grip is isn't too bad but it is heavier.
