There was a great thread last summer on the Achtung! line from this house, + Blackbird, but I recently looked for it and could not find it. Lost in the Huddler archive somewhere I suppose. Hopefully someone can dig it out.
Anyway, you are right on the money about Blackbird, and I am a member of the cult who think it terrific!
Adding by way of edit that BNer Chris Starker recently sent me samples of Devotion and Epiphany. I will make a point to try those this week and post impressions here.
