I think I could get by, in terms of a basic variety, with:
Lane 1Q
Haddos Delight
Orlik Golden Flake
Ruins of Isengard
of course this is a very personal list, based upon my tastes and experience only.
The Lane would be the primary smoker
Haddos, in a small bowled pipe, when I needed a new experience
The Orlik is really just a nice mild and easy smoke, similar to the Lane in those characteristics. Good for when you want a mellow smoke, but just not the Lane.
The Isengard is really nice to kick back with when sipping on whiskey.
