I'm waiting for an answer to your question myself, Charlie.
The few that I have smoked (Hyde Park & Caribbean's maduro) by "accident" in the last several years have been very mild with slight hints of a nutty flavor at best.
At worst, they have tasted like yesterday's newspaper sans the fish.
BTW, the Macanudo was one of my early "finds" as well.
I remember realizing the error of my ways when I followed the expensive 'nudo with a cheap 5 Vegas that blew it away!! LOL!!
That's my 2 cents. Maybe, someone can elighten us.
