smoking cigars that have been stored at 75% is not going to be pleasant.

Get rid of the crappy foam that comes with humi's and get some beads or kitty litter.

I recommend 65%. 70% has always been too wet for me - 65% is very safe and your cigars will smoke great right out of the box. I keep a lot of CC's and most of them are happier even lower, but 65% works.

I use HCM beads - if you want literally zero maintenance on beads...they are the way to go.
