A few things on the topic actually. I have been smoking a pipe for about 7 years now and have tried hard wood, cobs, and briars, and its the cob that I will reach for more and more these days. In fact I only pull out an old briar when I am outside working because I don't want to puff overzealously and burn out my cobs. Now that my fanboy rant is over, here is a question for everyone else. They are called Missouri Meerschaums for a reason, so what is the darkest one you own and how long have you been smoking it?
I would share my own but I had to start my cob collection anew recently for reasons I won't trouble you all with. So they all look rather fresh.
