Great thread. I don't have a list of bands I hate, but there are somethings I would prefer to see on bands. Kind of like fine wine, I would love to see more info, such as year, specific cigar name, size etc. I just got some new Lp9s and I have actually written on them the month and year that I purchased them. This way I can tell them apart form older ones that have been resting etc.
I like simple bands, the Ligas, and the undercrown are good examples to follow, simple but making a statement.
As has been said, the frustration of not being able to get the bands off without hurting the cigar bugs me as well.
