Disclaimer - I use a lot of hops in IPA, too. Ironically, I brew a lot of subtle, balanced beers too, but I hit IPA (and APA ) pretty hard, often IIPA level hops in AIPA. I used 19 oz in my last IPA FWIW. Satisfies my hop jones. golfgod04 - I agree with the advice from brewinhard about controlling the bitterness in software. IMO a BU:GU of around 1.2 is good for bitterness in AIPA, then all the other hops you add go to flavor and aroma (where I love them). My $0.02.
Edit - Have you used this many hops before though? It's hard to answer if it's 'too much' because we don't know your goals or preferences.
