I go through and move my sticks around usually twice a year. I find that burn issues can be humidity, it can also be if there is a lot of ligero or if you get a nice stem in a stick. I don't think there could really be much of a difference in a cigar from top to bottom like you are thinking however I could be wrong.
I've been experiencing more of my cigars burning unevenly. The only thing that I can think of is that the humidity, as it's absorbed by the cigar, settles to the bottom or lowest point in the cigar; causing the lower portion of the cigar to be moister and ultimately burn slower than the top. Has anyone experienced this and is the remedy, turning my cigars like a steak on the grill?
Got a cooler today...Preferences on shelving? Where could I get empty cigar boxes? It's just the smaller 28 quart orliter or whatever measurement (so that it stays full enough to stay consistent rh)
