The way that
@The Brew Mentor has the recipe put together, it'll benefit from very few tropical, fruity hops and more classic flavor hops. Centennial is the key to this sort of brew, IMO and sticking with a bold, smooth, citrus, earthy hopping really hits that classic American Northwest flavor profile. Amarillo definitely works great but if you start throwing a lot of juicy-flavored hops at it, that can jack up the perception of sweetness.
If I were brewing, I'd probably consider bittering with Warrior (though Magnum is my go-to) because it has a really smooth, slightly piney bittering quality. I'd stay very close to the "C" hops - Centennial, Cascade, maybe a little Columbus along with Amarillo and if I used something from the tropical palette it'd be Simcoe.
