This comes up occasionally... I'm looking for something for a son or friend... usually someone who doesn't want to smoke alone, which I understand. But, I cannot imagine worrying about picking out a blend for someone else to smoke. because really, pipe smoking is not really about finding one blend that makes the experience happen, but about just enjoying tasting, all of them, or exploring. Even the worst tasting tobaccos were fun to try. So, if keeping that other person smoking a pipe requires finding the perfect tobacco, then that may just be a symptom of a bigger problem, like maybe they don't want to smoke a pipe, or they aren't really getting into it.
This is the same reason that I am opposed to giving people pipes to get them started. If they aren't going to make the effort to buy their own pipe, to invest just a little into the experience, then they probably aren't going to stick with it.
Something given to you for free, just doesn't command the same admiration as something you worked for, IMO.
I know, I know, we all want a smoking buddy. But, sometimes the effort of "making" a smoking buddy outweighs the return.
