I go one shy of the extreme when using the inner or outer rings. I use all the cogs from the middle ring. With a 40 or 42 middle, I often don't ever need the others. A 36 (came stock on the Ram) is too small for general purpose riding for me). I generally run something like a 12 - 32 range in back. It varies from bike to bike.
