What I've found, once you go to a smaller ring guage you don't go back to the larger ones. I prefer corona sized and smaller. As far as draw, aging won't help much, some are just plugged. You can try taking it out of your humidor for a few days to dry it out a bit and it will help somewhat with tight cigars. Aging will help consistency, so that the entire cigar is at the same relative humidity, and not so that the inside of the cigar is more moist than the outside.
