I bring about 50-80 cigars broken up into 2 or 3 singles of most things I have... also, I bring out the rare/htf stuff I have. I love starting PPPs (even if it's only me contributing to it) just so people can try stuff they may not have ever had before. To me, sharing cigars and cigar experiences is the best part of smoking and collecting.
Oh... forgot to answer the other part of this. It's usually all CCs, because that is 97+% of my collection
