I picked up a couple bottles of their BIB product when we drove through Kentucky last year. Just opened the last bottle the other night - delicious. Rip, I hadn't been bothering to water things down to 80 unless they started out significantly over 100 proof, but you're right - it's a big improvement taking it down to 80-90 proof.
Man, none of the Elijah Craig stuff has ever done anything for me. I'd rather drink Old Crow, and I infinitely prefer regular ol' Buffalo Trace.
