remind me to trade with Sli sometime!
67%is good enough, although it's not that hard to get 'em to 70 when they're empty.
humidity should change when you fill 'er up, but don't expect it to change overnight.
climate and humi location are obvious factors in how much maintenance is required.
some cigars are "wet" when ya get 'em, fresh ones mostly. by wet, i mean very moist, not drippin', so i believe that has an effect, although not very big.
i usually don't seperate my cigars, usually put 'em all together. i don't think the flavors marry into each other, with the obvious exception of "flavored" cigars, and i put mine in naked,(no condoms on my stogies)
some of the vets may have different opinions on this, so take all advise, and do what seems logical to you.
just remember winter is comin', and if you don't live in a humid climate, you may need to add humidifiers. i use 2 round 1's in my 150, along with 2 drimistats, and in the dead of winter, sometimes i can't keep it above 63, because of the dry air. hope this helps some.
