Why the 25 minute hop addition?? You'll get more bittering from it than any flavor (after 15-20 minutes in the boil you won't get much flavor from it). I'd move it to either 15 or 20 minutes.
Personally, I don't care for cascade hops. Maybe it's due to how a local brew pub uses them in pretty much everything, so that's all you taste for hops. Plus, they tend to over-hop the batches (IMO).
I did a MO SMaSH with EKG and it came out great. I brewed a second batch (10 gallons) so that I could fill three kegs (3 gallon kegs) instead of just two. I might brew it as my first batch in my new place (planning to move before end of August) so that I have enough on hand.
