Well, the Maduro's going to be a lot different from the natural Corojo wrapper... I had a Diploma Maduro a couple weeks ago which was very harsh, but I think it was dry. I smoked it the day it was delivered from c.com. I let the rest of my order sit in my humidor for a week and haven't had any other bad sticks out of that batch.
I'm going to give the Ltd. maduro another try. I've also got a natural wrappered Ltd 11/18 here I still have to try.
So far I've had a regular Camacho Corojo (forgot size), which was good, a Coyolar Titan which was absolutely great, and an Ltd Dimploma Maduro I think was dried out.
