I have toted 25 lbs of Mamiya and Nikon around for years. Not to mention Linhof and Bogen/Manfrotto tripods and heads. Seems to me that 5.5-6 lbs of MF camera are light in comparison. And I'm 57. What gives with all the complaints concerning how "heavy" the RB is? Every review I read was a negative concerning the weight of this camera. I look towards the one key positive: the photos. It seems a winning trade-off to carry a bit more weight and get beautifully focused and exposed photos than to carry around a pound and a half 35mm and pray they come out. That's just me though.
