Extract Recipe for a Black IPA

If I could ask one last question, what type of hops could I use with the Cascade when I dry hop? I would like to get quite a bit of hop aroma. I also plan to toss in another half ounce of something at flameout.

I am going to us remman's recipe listed above.

EDIT: I am also wondering if there is another name for Canadian 2 row LME. I can't find it specifically named at any store.

ONE MORE EDIT: When choosing my yeast, do I risk messing up the whole batch if I switch out the S-05 and use S-04 yeast?

2-row is just plain light LME
US-04 should be fine, just a touch drier perhaps
Cascade is a great dry hop and pairs well with centennial, Amarillo, simcoe, and citra
