I did quite well with this AIPA recipe in the Welsh National HB comp back in sept.
It might make a good starting point for a recipe. You could sub out any of the hops for other suitable New World varieties - in fact I wasn't overly impressed with the Denali leaf hops I used in the kettle, and am going to change these for Simcoe when I brew this again at the weekend:
