Magnum Opus, Beverwyck, Sunjammer, Ambassador and now White Knight have all been great smokes.
The only one I still haven't tried that I'd like to is Black House.
I am a huge Beverwyck fan. Sunjammer is decent, and I went through an Ambassador phase. Have Sunjammer and Ambassador on long term cellar duty, currently. Magnum Opus didn't do much for me, and the Black House didn't either. However, I was sent a double order of Black House on accident by PipesandCigars.com (I told them they doubled the order, and the replied, in essence. "you should go buy a lottery ticket, have a good smoke on us", so 4 ounces are cellaring for the long term, so maybe it will improve to my tastes over time.
I think if I had to take just one or two tobaccos to the desert island, it would be Beverwyck and Mazatec.
May have to try the White Knight.
