I was talking to a prominent pipe maker/tobacconist recently as I enjoyed a cigar in his lounge. This guy has been in the business for over 40 years so when he talks I listen. We got on to the subject of ghosting and he said it is very over exaggerated! His comment...smoke what you like out of any pipe. You might pick up hints of a previous smoke but it is so subtle it doesn't matter. He said he smokes aromatics, english blends and virginias all in the same pipe and it has never affected the quality of the smoke. What are your thoughts?
