Without exception I use 2-3 cleaners during a smoke. A dry pipe tastes way better. It is not a nuisance because it has become so automatic I barely notice it. I buy pipecleaners by the case.
I have the opposite happen. One of my cobs is a straight pointed-end egg and I have yet to get through a bowl without having to run a pipe cleaner through it. It also happens to be entirely too open for my liking, which undoubtedly has something to do with it.It is never needed when smoking my cobs though.
