Very interesting recipe and very encouraged by all the feedback. I'll be attempting this one tomorrow, only difference is that my LHBS is completely out of centennial and magnum so I'll be substituting the magnum for columbus (13.9) and I'll be using almost 2 ounces of cascade (3.8) to replace the centennial. I hate not having the right hops on hand. I'm open to comments if anyone thinks these substitutions aren't right.
