Midwest's "Ferocious" surly furious clone

I brewed this today, seems like it will be good, very hoppy, anyone have any experience with this one? I'm curious how close to the real thing it is.

I did the Northern Brewer "Shirley Furioso" kit a while back, and then made a few tweaks in it and made it again.
