If you are used to smoking things like Anejos, LFD, Camacho, Diesel, Liga Privada, JdN, Padron Anniversary cigars, and probably half of what comes out of Nicaragua these days, etc, you will probably never find a Cuban cigar that you think of as "strong"
Complexity is an interesting thing that means different things to different people. It can also be more obvious in some cigars than in others.
