Not to shoot any holes in Jonsey's reply, but.....
the "loose cigar" thing is a variable.
Some cigars may be packed more than others, others less. This is one of many ways to affect a cigar's burn and flavor.
Now when I say loose, that's difficult to explain here in print. You'll see as you smoke more and more and can compare the major brands.
Granted a quality cigar shouldn't be "squishy". Some give or squeezability is normal. We are dealing with a leafy, organic material here! It will vary from brand to brand and type to type.
The only thing one could tell from GENTLY squeezing a cigar is uniformity. However, I don't recommend squeezing your cigars. You risk cracking the wrapper.
The crackling sound bit is a myth. ANY cigar will make that sound when gently squeezed and rolled between your thumb and finger, but yes a DRY cigar will do it much more. It's a poor way to judge a cigar's rh.
So, IMO, there's no way to tell you how soft any given cigar should be at 70%rh. I wouldn't sweat it as long as your rh% is under control.
My two cents :smiley24:
