Hard to recall but looking back through my bucket-

La Escepcion Exclusivo Italia EEM Nov '11
GoF Serie B GT 2011
Viaje Zombie Black
Padron 1926 80yrs Natural
OpusX No. 2 2012

Were all excellent smokes but I think the winner goes to

Montecristo EL 520 AME SEP '12



Which is interesting because when I smoked my first one a year ago, which I bought at a LCDH, I wasnt impressed. Muddy, flat and boring are words that I recall using. The first one had a much darker wrapper and the profile was completely different from this lighter wrapper. Some FoGs will tell you that wrapper does not affect the flavor of CCs, well I can attest that is utter bs. Moreover some vendors charge a premium for these darker wrappers, not always best imo.
