Undercrown Corona Viva and Papas Fritas are the only ones in my regular rotation. I've smoked a fair number of #9s and T52s, which I definitely enjoy, but are a little more than I care to spend. I burn through Nica Rusticas from time to time, too. I like HE's quite a bit, but don't normally buy them. Not sure why.
I really don't care for the KFCs. The fire cured tobacco tastes like campfire or burning leaves to me. Just not at all what I'm looking for in a cigar.
