When I first started smoking, Fuentes were the promised land if you could find them. I grew away from them for a long time. I'd smoke an occasional hemmingway (didn't even know there was a maduro) but was not all thet impressed.
This winter I stubled accross a few 49s and WOAMs. Still have not smoked the WOAM, but the 49 was excellent. It made me lust after the Shark. A quick trade with mrtelcom (thank you sir) and now I have one. But I don't have the heart to smoke it yet...what if I like it and can't get any more.
The ashton maduros I find them to be the best mild maduro out there. But most Fuente products don't excite me. Opus X are a good change of pace but I would never seek them out.
The same is true with CAO. I love the Brazilias and the Italias and have smoked most the rest of their line. Good not great (except the above).
Padron is the only line which I have not found a cigar I don't care for. I even like the ocassional fuma. I'm not sure what it is.
