I've been smoking cigars seriously for about 7 or 8 years and I like to experiment with things. I'm not afraid to try different things or consider different ideas. I discovered a few years ago that dryer cigars smoke much better and I have allowed my aged, ready to smoke cigars to get rather dry before I smoke them, some people call it dryboxing. I almost never ever have a plugged cigar.
I have had lots of cigars that were as hard as a rock that smoked perfectly, perfect draw, perfect burn, bursting with flavor. For long term storage of course you would want a higher level of humidity, but for smoking, 55 to 62 percent is prime IMO.
A hard cigar is a cigar that was bunched tightly and the cigar is packed with tobacco. If it was bunched properly it will still smoke just fine. I have had fresh cigars that were extremely firm with almost no spring or spongieness. If allowed t dry they would be hard as a rock.
Too many people obsess about maintaining ideal temperature and humidity. My advice is, don't woory about it that much. The thing to be concerned about is OVER humidification. What you get with over humidification are a host of problems. Cigars tend to have a tight draw or be plugged, the burn is generally not as good and some cigars can develop a sour or off taste due to over humidification. Mold is another unfortunate result of over humidification.
These are just some of my observations and experiences. Some people like their cigars moist and fresh, some like them dry and firm. It's a matter of personel preference. My preference is on the dry side and I've had excellent results.
