I love all the Hops you listed, and have used LOTS of summit in my big IPA's / APA's. I would also recommend a Summit and Riwaka hop combo. The Riwaka is hard to find, but I just did one with it and it has a wonderful Tangerine flavor. I think I found them at Austin Homebrew.
+1 on King of Cascade's comment.. use the 1oz if you are making a big IPA, you wont regret the smooth fruity bitterness.
