There's nothing wrong with cobs. Let me say that again: there's nothing wrong with cobs. But to my sensibility, according to how how I view them, there are several things wrong, and I just don't like them, mostly due to the fact that they can't be finished or shaped, and instead of looking at the warmth of wood, one looks at a series of gouges. Sorry, but that's God-awful.
I was looking at an Adam Davidson smooth bent billiard in a deep brown. I don't particularly like brown, but I found myself really enjoying it's lush richness. A cob is never going to have wood so finished.
And you're never going to see a cob blowfish, as in SP's American estates by Todd Johnson, every facet impeccably showcasing another facet of grain.
So if I choose to smoke a cob, the only thing left to admire is its abject simplicity, but if I do, "I'm going to end up thinking "why didn't I smoke a briar?" because or me simplicity is not enough.
But I know for many of you it is, so I'll shut up now and let you go back to smoking them.
