They were as varied as we are. Heck, I'm sure someone smokes Englishes in chimneys, dublins, and whatever. There's no law to what is smoked in which pipe. Seeing as how we are a very small cross section of the whole pipe smoking community, with the majority smoking aromatics, I am sure that there are all sorts variations to what, why, and how what is smoked in which pipe.
Sorry, I sometimes type too fast and get confusing, ha ha.
