After my recent experience and experiments I have decided to pull out my better briars out of the aromatic business. Therefore I have decided to experiment with corn cob pipes for aromatics. I remember reading somewhere that many people prefer them for aromatics, as they smoke cool and preserve much of the aroma. Although I have bought one because it was cheap, I have never used it - I guess I had some sort of prejudice against it. Any road, before lighting my first I thought I should ask the corn cob gurus here a few questions. Does it need breaking in? How long can you use it before you throw it away and buy a new one? Is cake ok with corn cobs - some articles suggest there shouldn't be any cake, while others seem to imply that some cake is ok for prolonging the pipe's life. Any other tips are welcome, guys.
