A couple of years ago, I set a goal for myself - reduce my gear to two or three 4x5 cameras and a handful of lenses. I never quite achieved that goal but, I did get rid of most all of my excess and I do really only use three 4x5 cameras anymore (even though that leaves a few to collect dust.). I recently bought a nice 645 camera and it has replaced all small and medium format gear.
Here's the thing...before I slimmed down, I had too many choices...and it was often more than a little paralyzing.
It may seem counter intuitive but, having fewer gear choices really is liberating.
