Quick question. I'm reading in here, trying to get my learn on. It seems that you don't want to only have one pipe, because the tobacco will "ghost", or impart a flavor on the pipe after a while. So, with that...what are the different types? The only two I seem to be able to find are regular and aromatic (sp?). How do you tell the difference? Is this like the difference between Habano and Maduro, or infused and regular? Right now, it seems easier to say "This pipe is only for CAO blends".
