I'd like to follow up with a slightly tweaked recipe of more what I would do. Wyeast 1056 has an alcohol tolerance of 10%, so I would probably use something a bit tougher.

Mash instructions on page 2.
There are no rules, to my knowledge, that state an Imperial IPA must follow a 1:1 BU/GU ratio. That is the minimum ratio I would follow, but the bittering could definitely be heftier. After all, this is not a regular, low abv IPA.
