Two pipes for every day of the week- plus a few back-ups. A briar for at-home-smoking, and a cob for when I'm out and about. If I spent more time at home, I could probably get by with fourteen briars, and seven cobs. I think a briar pipe is good for a day, provided it has two or more hours to rest between bowls, and seven days to rest between days of use. When I smoke from a cob, I'm not particularly worried about nuances, flavor, and relaxation. I'm more concerned about avoiding my brain hemorrhaging from moron drivers driving too slow in the left lane on the interstate.
