I just finished an experiment in an attempt to lighten my bag, and wrote an article on the results. Hopefully someone here can benefit. Sorry it's not a short article.

I don't want to be rude - I'll put an overview here.
I've been on Phase One for a few years (DF+, 45/80/150), (Guy is to blame for that) and only do Landscape. Anyway, I didn't jump on the lighter-is-better bandwagon because I felt (and still do) that I need the quality that I get from the IQ260. I don't print large just for fun. I print large because it best represents the subjects I shoot and my vision for the print.
Having said that, I've obviously run into the trials of the bag getting too heavy to explore the way I would like. I'm 54 years old, (is that old?) and healthy, but the knees were having a hard time with a 30 lb bag after a couple of miles on tough terrain.
That's the background. The solution I found, with getting the weight down as the objective, was to move to shooting the Cambo + IQ260, (leaving DF+ and lenses home in studio) and bringing a Sony A7 along for detail shots. I tried this out last week and am very pleased. I ended up downgrading (lightening) my tripod and ballhead as well, and some of you may enjoy reading about the results as I've come to the conclusion that we may be carrying more tripod/ballhead then we need. (at least sometimes)
As always, these things are very personal, and what works for me won't work for someone else. Still, the end result seems good as I didn't sacrifice quality, and I don't mind using the Tech camera workflow a larger % of the time.
You all have given me lots of great information here, and I wanted to give something back.
