For people new to pipe smoking, who don't know their preferences so well, a pound is probably not a good bet. It might be something that will be enjoyed over time, but often tastes change. But if you've been at the pipe for a while, and you've zeroed in on what you enjoy as a base leaf, what as condiments, and flavoring if any, and brands and cut, you can usually order a pound, even when you don't know that specific blend, and come out alright. Otherwise, give it away to friends, trade it for something else, or let it age in high hopes. I've been enjoying a wide variety of blends, so I don't buy a pound more than once a year.
