There's a lot to be said for the instant, intuitive connection, but there's also something to the process of adapting yourself to a new piece of equipment.

8x10" had an immediate appeal for me in a way that 4x5" didn't, but after shooting 8x10" for a few years, I got a 4x5" camera for when I want to be more quick and flexible and I really enjoy using it. Nothing beats a large contact print, but on the other hand, my 4x5" Technika is the most versatile camera I have.
