Hi! I've been getting pretty frustrated with my briar. It smokes well until I reach the bottom. I can't seem to keep the bottom part of the bowl lit. I just end up wasting a lot of tobacco. It gets really sticky and won't light for long. When I take the tobacco out there is a sheen of sticky stuff at the bottom of the bowl. This doesn't really happen with my cobs. Is this just a matter of breaking in the pipe? Should I really expect this from briars? Bad technique? Or bad pipe?
