BUT..., I must say that there isn't one that I don't like. It all depends on my mood. I like Cameroon, Colorado Maduro (reddish maduro), Colorado, Sun Grown, and even Connecticut wrappers. I have very few Oscuro wrappers that I enjoy.
Noticing that maduros seem to be garnering more votes than any other, I find that interesting... 20 years ago, I would have said the same. I wonder if the amount of time smoking cigars makes a difference???
I'd like to postulate a theory... (please chime in, as I am very possibly WRONG)
THEORY: Maduros (I am speaking of the very dark maduros) are the cigar to which those in their first few years of cigar smoking, gravitate. As cigar smokers mature (don't know if that is the right word), they gravitate to spicier wrappers.
