As many have said, Opus and CCs. I also think that a lot of maduros do great with a few years of age. They even out some and can produce some really rich and smooth flavors. I smoked all I had but the X000 series with a few years is awesome! Same with Fuente maduro churchills, Aroma De Cuba Mi Amor, 601 Blue, Kristoff Maduros, Sancho Panza Double Maduros, I'm sure I'm forgetting some.
