I like it. I don't do a double but have a house black IPA I like that uses Cascades, Centennial and Williamette. I don't use much WIlliamette in my brewing but I do like it in my black.
And, I love Chinook as a 60 minute addition.
Never used candi sugar either. Might have to give this one a try one day. Let me know how it turns out.
Wherever you go, there you are!
