I'm with you - I like the MX2 but I don't love them. For my money there are better double maduros (or cigars that taste as maduro-y as double maduros) out there, and I humbly think my own double maduro home rolls are better. Surprisingly, the Sancho Panza MM are good for the money as long as you don't try to over-rest them - they're really good ROTT or within a few months thereafter. I like the Quixote best - the longer ones seem to get wonky-flavored past halfway.

Famous Smoke's Final Blend tastes like a double maduro, but I'm not sure it is. The Indonesian addition to the blend gives them a nice extra sweetness. But I'm a big fan of Indonesian tobaccos - YMMV.
