Not sure it's any less tedious, maybe the DFKs are a tough matchup because ODF is in my top 5, I can't fault this tobacco in any way (for my taste)."There are other blends which I liked, but there are others like them I know I'd always prefer, case in point is HH Old Dark Fired (made the cut) vs HH Bold Kentucky and Lakeland Dark (both failed)."
I think this is rather brilliant. You are forgoing evaluating each blend on its own merits, which is the usual approach and which of necessity demands a rating scale, which is a PIA (pain in the ass) and then demands a massive contrast and compare.
No, you just group similar tobaccos and ask the question which would you smoke first. A simple, expedient that gets you to the answer with much less work and thus more quickly.
