I'm with 8-5-8 on this. I prefer my smokes on the dryer side. I keep my humis at around 60-63%, and will even pre-cut, and dry-box certain cigars, before I light 'em.

CAO's especially seem to like a lower RH. If you've ever had a cigar that seems to burn hot, and have a quite a bit of harshness, try letting them dry out a bit.
