I had all sorts of burn issues before I dropped rH. Not to mention bitter, nasty tasting cigars.
I have 65% heartfelt beads in 2 humidors which seem to hold around 62 to 63 and the burn issues are gone.
I store my hoarded stash with Boveda 65's in airtight containers so those sit right at 65%
I highly doubt just leaving a cigar out for a day or two is going to totally fix things although it will probably help some. It takes a cigar a while to dry out and in my experience, by the time the filler is dry enough, the wrapper is splitting or ready to. The only real way to do it is to lower your rH media and let them acclimate.
