One of my "tricks" when deciding what hops I'd theoretically use in a brew is to find a passably good commercial brew I like.
The wife - bless her heart - bought me a No Name pale ale strictly done with Citra. The best description I could give for Citra would be grapefruit and pine needles. In another instance, I asked her to buy a mixed case of Harpoon Rye IPA, Big League and Rec League, and the Bohemian Pilsner. I absolutely LOVED the bittering and aromas of the Big and Rec League beers.
Harpoon uses Citra, Mosaic, and Motueka and it works. I particularly like the Mosaic - it's a great hop, but if you do any sort of dry-hopping be prepared for some haze!
