I've searched and read what I can find about burn lines (yes, I'm a little obsessive about it, a little problem can become a big one if you don't fix it) and the prevailing wisdom is to put the slower burning side down. This works for me a significant portion of the time and I really don't have too many burn issues since lowering my rh to 65%. But...in the last month I have had 2 cigars where putting the slow side down didn't work, but when I put the slow side up it corrected. Are there just different cigars that will respond differently to which side is up? Could it have to do with how tightly packed they are? I would have thought it might be the scotch or tequila, but both times it happened when I was drinking coffee with my cigar. And....discuss.
