For Horizon 11% AA, and Warrior 16% AA Hops. Can't seem to find these.
Both of these varieties are relatively new from what I found so info can be limited.
I did find on Brew Your Own a table of substitutes.http://byo.com/referenceguide/hops/
They are both listed, you'll have to go to the next pages to find them.
Good luck substituting, don't forget to calc your AAU's so you hop at the same rate as your recipe calls for in the addition schedule.
Thanks for the imfo!
