real or psychosematic

1a) In your experience, is there one distinctive flavor/aroma characteristic that is solely found in Cuban cigars?
1b) Have you found it present in ALL Cuban cigars?
1c) If you have found them so, describe the "smooth" characteristic that is present (according to your experience) in Cubans -vs- Non.

I wouldn't say that there is a flavor consistent to ALL CCs, but certianly the characteristic is the smoothness. I'd classify the smoothness that even the heaviest CCs I can nose about half a pull, but most times I can nose the whole thing. With an NC even the lite ones, nosing them is a bit like sticking a live wire in ones nasal cavity, its almost harsh enough to bring tears to the eyes.

I'd also say that a lot NCs get credit for "flavor" where all I get out of them is "strength". But thats just my take.

2) Is the difference (as may have been noted in question 1) that significant, that Cubans are so much better?

For my tastes pretty much yes. There are some CCs I don't smoke but the ones I really like I prefer greatly to NCs. But I'm also the type of guy who can make 10 lbs of lasagna and then eat it for 2 weeks. So its perfect to me to own like 175 Cohiba Lanceros and smoke those heavily. Its just my make up.
