I've smoked a total of two bowls and both of them have burned all the way through without a relight. Now, either I'm the most efficient pipe smoker of all time, just dumb lucky, or I'm doing something goofy. (History indicates the latter is more likely.) I enjoyed both of them, so what's not to like. I may have been smoking a bit to hot/fast. I felt like I was taking my time, not rushing, just keeping it burning...enough? Maybe I'm just a prodigy (at age 43) and someday I'll make all the way it to the Piper Olympics. Yeah, not so much. More likely I'll burn a hole through the bottome of my cob. I'll keep reading and smoking and see how this turns out.
