It's simple, I enjoy aros now and then, possibly because I'm not as discerning as so many of the members and simply desire a couple of blends that give me a simple, not unenjoyable experience. Some smokers enjoy searching out new tastes, prefer certain styles (even to the point of disdaining other smoker's choices now and then) of blends, or simply are unable to find a couple of blends they can enjoy pipe after pipe. Me? I'm one of those guys that prefer my diversions simple, no notes, no chase for ingredients, no thirst for discovery, no anticipation when a package arrives with blends untried.
An aside: The smell of newly uncapped or unsealed blend tells me nothing about what to expect when the leaf is ignited and tasted. I find, I stress I find, no connection at all. Probably just me.
