The Bourbon Bleu, Oak Alley and Bayou Morning Flake are ones that I'd like to try some day.
Three Friars is the only I've tried, and I loved it. Not sure if it is topped with anything, or what it is cased with, but it has such a nice and subtle soft vanilla-caramel note. Somehow simple while being full, uncomplicated while being intriguing throughout the bowl.
I also have a Bijou cellaring. I'll try to get it to 5 years (currently about 2 years on it). And then I have a few other C&D tins cellaring, plus my fave bulks in jars, including Super Balkan and Stratfordshire. I definitely jive with what C&D are doing, but there have been a few I'd simply never buy again (including Pennington Gap and Autumn Evening).
