Never had a stone pipe before, so thought I'd try to teach an old dog a new trick! Only change I made was to replace the river reed stem with something that was more natural for me. First attempt at the new stem, had too small of an airway. Baccy kept clogging the hole, so opened it up a little, and WOW! Smooth lite smoke from the first draw! The stone adds no flavor to the baccy, so what you put in is what comes out. Think I got a keeper! Thanks Rekamepip!
