Re: question about havana
Havana is pretty popular here in NYC. The three most common brands are Havana, AF and Romman, then a few of the stores carry StarBuzz.
I like Havana. It's a mellow smoke, and the flavors come through strong after it gets going. However, the flavor and smoke isn't as harsh as AF can get so it's great for when my fiancee smokes with me, since she can't handle the harsh smoke that well.
It isn't as moist as AF, which I think is the reason it isn't as "potent", but it's a perfectly acceptable tobacco. My favorite so far is banana & honey.
