I'll join the chorus of Sotnsipper, Funknik and Illfarmboy. I love Dickel No. 12 for its more Bourbon like qualities (it also makes the best Manhattan around).
I can't say I like any of the other Tennessees I've tried, which includes: JD 7, JDSB, Gentleman Jack and Dickel Barrel Select. All of them are too sweet for me. I've never tried Dickel No. 8 but would certainly like to if it ever comes back.
