I brewed this (modified) yesterday - my first all-grain batch. I hit a gravity of 1.042 and filled my bucket right to the 5 gallon mark. Modification - my LHBS didn't have centennial hops, and the cascade he had was 6.9%. So, I bought an ounce of that, and used a quarter ounce for each of the later two additions (as per the recipe). For the earlier two additions, I used a quarter ounce of the cascade supplemented with ~.05 oz of some warrior hops I've got. I'm sure it won't be exactly the same, but it should be quaffable. It was bubbling away nicely this morning!
