As a MF RF user, there aren't interchangeable backs so I never got to rely on that feature. If you just shoot B&W mainly I think it will be simple enough without changing film.
I tend to be hesitant about shooting 400 speed film in daylight, but that is mostly because where I live the sun is intense, and most days are completely cloudless. On a leaf shutter SLR 1/500 is my max, and that it doesn't really reach (I came across a magazine review of the Bronica SQ where they tested the shutter speeds on a brand new lens. It was pretty accurate up to 1/250, but 1/500 was only halfway between 250 and 500 on a brand new lens, so I don't usually use 1/500.) ISO400 means ƒ22 and 1/250 on sunny days, whereas TMAX100 could do ƒ11. But yes if I only do B&W the swappable backs become less critical, but I can still imagine I'd have all 3 B&W film types loaded and swap out between 100, 400, 3200 based on the context.
I could easily fit a 4th back for something color like Pro400H, but my thoughts (and kind of the gist of this thread..at least its initial purpose) are less about technical solutions but rather about simplifying my thought processes...it is my vacation afterall. I mentioned this is a previous post that the rule could be simple--indoors or heavy clouds: Tri-X; Outside: TMX100; In the sewers (or night time or other dark interiors) Delta3200.
On the positive side, lack of color film means I don't have to ask myself--"do I want this shot in color or black and white?" On the negative side (and my primary concern) not having color film means if the answer had been "shoot color" that is no longer an option.
