It's good stuff - I like it better than the OB 10 because it's about the same price ($60 US, I believe), cask strength and non chill-filtered. Otherwise, very similar taste profile.
Speaking of Blackadder Springbanks - has anyone tried the 1965? It's about $330 a bottle here, which is slightly out of my price range...
