Great topic, I'm about to brew a red/amber ale with Citra and Cascate (Two Birds Sunset Ale Clone-ish) so very relevant. I think I'll aim for a hop schedule similar to that reccomended by Yob. Will let you know how it goes.
I made my attempt at Sunset Ale on the weekend, brew went well. The citra hops smell amazing. It's currently fermenting along nicely. I will post the recipe on the forum when I'm on my home computer next.
