I've been smoking cobs for five years and have recently branched out into briars. I find that I get more unsmokable wet dottle smoking my briars, whereas the cobs smoke dry to the bottom. Cobs seem to be more tobacco-efficient for me, wheareas when I smoke a briar, I end up tossing about an eighth of the tobacco at the bottom of the bowl which is soaked with moisture. I believe it's because the cobs are more absorbent and the moisture collects at the bottom below the stem shank. Anyone else experience this?
