I'd definitely agree that NC's go past their prime earlier than CC's since that has been my experience too. But I was recently surprised and caught way off guard by what I found with some old Padron 1926 cigars. The cigars were rolled in 2007 and absolutely wonderful when I bought them (2007). Then I forgot them and when I rediscovered them in 2012, I was severely disappointed by them. I've tried one every year since 2012 and they've been flat and boring....until last month. They hit their peak again and I was in disbelief. I pretty much smoke CC's exclusively now, but these things are phenomenal. I've nearly smoked the remainder of the box now. My point is, you never know when I cigar will go flat and you never know when it'll come back to life. If they're smoking the way you like them, then enjoy! If not, don't be afraid to give them some more time even if it goes against conventional wisdom.
