I remember what seems like a lifetime ago, my grandfarther (a life-long piper) telling me "son always rest your pipe after smoking it for a while". I've practiced this belief and it has served me well, resting a pipe for a few days at least after smoking it for a week or so. It has worked well for me and also lets me rotate my pipes (because that special one is the one I tend to want to go to more often). Just wondering if anyone else follows this practise.
