I'm gonna brew tomorrow (first for a month or so) and I want to use what I have in store rather than go out and buy more "stuff". I really need to use up some stock

Anyway I fancy brewing an APA for a change. I usually stick to British Ales but as I have some Cascade and Citra I thought I'd go all Yankee Doodle Dandy (Copyright alert !!! that's a great name for a beer

I've come up with this using a recipe in a book I have and what I have in store. What do you guys think ?
I normally do a 90min Mash and Boil, the recipe calls for a 60 min mash and Boil. I may stick with 60 and save an hour.

The bittering hops used (Northern Brewer)are what I had in stock. These can be changed to your liking, along with the Aroma hops if you feel so inclined. The OG can also be increased as desired, I dropped it to 1.052 from 1.056. The efficiency was dropped from 83% to 80% to reflect the gravity, this may need adjusting to suit your equipment/records.
