I've found that I enjoy my cigars more when my humi is at around 65% humidity, but I only started smoking this fall (and I live in the Milwaukee area).
I know I stressed out about the cello on/off debate as well, I took pretty much all of the cellos off my first stash, and now I wish I hadn't. Having the cello on them makes it so much easier to move them around, and more importantly give them to other people!
