I have two rangefinder kits in Lowe-Pro bags that I just grab and go.
One kit has two Canon P bodies with 50mm f1.8 lens, 35mm CV Color SKopar f2.5 and a
Canon QL-17 GIII.
The other kit has a Contax IIa, Contax IIIa, with 50mm Sonnar f1.5, Biogon 21mm f4.5, and a
Canon QL-17 GIII.
My 35mm SLR Kit has a couple of Nikon F3HP's with 24mm, 55mm Micro, 85mm and 180mm f2.8 and a
Canon QL-17 GIII.
My next kit will have a Zorki 4 with 50mm and a
Canon QL-17 GIII Both of these are going to have new red leather covers to help them take better pictures

.
My coat pocket cameras are a
Canon QL-17 GIII and a Rollei 35S.
Just in case you can't tell, I like the QL-17 GIII. I like being able to shoot infrared film in one with a 25A filter and being able to see to compose my photo.
I have never once uttered the phrase "Umm, here hold
this while I try to load film into this camera", when using a QL-17 GIII. It is just drop the film in and go!!
My theory is if you have something that works, stay with it. The QL-17 GIII's are better cameras than I am a photographer.
