Not sure what you call this phenomenon, but "on occassion" I will have a cigar burn quicker around the outside with the filler sticking out like a hot poker...still burning, but I don't seem to be getting much from the draw. I've learned to just guillotine cut that part of the filler at the base without cutting the cigar. Seems to work fine from that point. Curious to know if others have had a similiar experience.
