All Amarillo APA Extract Recipe

Hey All,
Wanted to get everyone's input on my All Amarillo APA recipe...specifically the hop schedule & IBU's

I plan on doing a series of single hop brews by sticking to something similar to the below base recipe but changing up the hops.

Figure Amarillo is a pretty darn good one to start the series off with.

Let me know what ya'all think! Cheers!
