Inward burn, touch up, purge, inward burn. You get the idea. Every friggin dark wrappered cigar that I smoke does this! Undercrown, #9's, Partagas Blacks, My Fathers...you name it. It does it. Smoked an Illusione 4/2 just now, same $hit. It had been in my humidor for 3 weeks Boveda'd at 65%. Just to make sure I wasn't going crazy I lit up a 5 Vegas gold, Connecticut, and am almost to the band with a dead nuts perfect burn. WTF??? Do the liga's need to be burning hotter? Should I dry box the one I want to smoke for a few days beforehand or should I just stay the F away from really dark wrappered cigars? LOL!
