I made a citra/amarillo pale ale for Christmas, it was out-freaking standing. Grain bill was about the same as Tasty's APA. The Citra smelled incredibly strong from the package, and these were the 2009 crop. Definitely the strongest smelling hop I've had, almost like a citrus aroma that burned the nose. IIRC the recipe had a FWH with amarillo, a small magnum addition at 60, and 0.5 oz each of citra and amarillo at 20, 10, and flameout, 1 oz each dry hop. The beer had great aromatics and tasted strongly of grapefruit. Since the beer was only ~25 IBU it was not bitter, but I absolutely loved what the Citras did to the beer. I think that it maybe overwhelmed the Amarillo, but it was still awesome.
After about 5 weeks sitting in the ~65° closet, the hop character has subdued substantially. You get a better balance with the malt now, but I think this beer was best as fresh as possible. Cold storage probably would have helped.
