I have a feeling that the answers will probably always depend on whether we speak in terms of work or hobby.
What makes sense in a pro situation doesn't have to hold true where the option exists to wander out with a single body and fitted optic and fear no loss. Work, for me, often meant the entire range had to accompany me, but for fun alone, a concept which never came into play until post-retirement, I would never dream of burdening myself with lots of stuff. Indeed, it is the perfect turn-off for me. I like to be able to concentrate with a single point of view; at times, even that becomes too broad and might create doubts. Fortunately, I have learned to go with instinct every time. Come to think of it, that puts me in company with Mr Eggleston, not my greatest influence.
