I keep some at 62 and some at 65. They all seem to smoke well, taste good and burn nicely.
OP, when I started out I had the same questions about aging, resting and best RH. Most here feel aging doesn't really begin until you have had them for 2-3 years. Before that is resting. The purpose of resting is to allow you cigars to fully acclimate to your preferred RH. They change somewhere around 1% per week when resting. A fully acclimated cigar is at your preferred through out the cigar. The center is the same RH as the wrapper.
If you buy more cigars than you smoke it won't be long before you have some rested cigars and if you keep it up you will have some aged as well. It just happens and nothing to worry about.
