How do you determine which tobacco to smoke with new pipes? I break all my pipes in with a Burley, but after a few smokes I pack it with another tobacco. Is there any reasoning behind it or is it just whatever you feel like? I have smoked one type and switched. This does create problems with flavor profiles, which is why I like to make a decision that each pipe will only smoke (in general) one type of tobacco. Are there any opinions on this?
