Yep, I use Warrior as my bittering (60-minute) hop addition in my IIPA. Good stuff. Use it in an IPA/IIPA and early in the boil (although you could really use it anywhere you want).
only ever used them for bittering. An ounce went really well in my robust porter with i think willamete as the flavor/aroma hop. Its a nice clean bittering hop.
Warrior is a good hop for anywhere in a brew for ales. Great for bittering with its high alpha acids. Magic Hat here in VT used 100% Warriors in their HIPA before the hop shortage made them switch to Columbus and it was the best beer they ever made in my opinion.
I've used it mostly for bittering but plan to use it in an IPA this summer at every stage of the boil with other C hops.
