I've been dedicating pipes to different types of tobacco (one for aros, one for Latakia blends, one for Va/Pers, one for codger Burleys, etc., with a bunch of cobs for good measure), but it's less about fear of ghosting and more about not knowing enough about variations of flavor to determine whether or not I've got a ghost. I just figure that, for now, it's easier for me to experiment within the broader categories if I'm not second-guessing myself about whether the flavor I'm experiencing is the tobacco I'm smoking now, or the tobacco I smoked last week. :lol:
