For hops on hand I have cascade, amirillo, delta,nelson and magnum. I was thinking the all centennial would be Two hearted like. Any suggestions to help me out?

I like it- I like it a lot! Looks great.

I dont think that recipe needs any help, but you could add some of your amarillo or nelson for flavor/aroma. Looks good as is though.
