The specs put it in DIPA range but you have no flavor or aroma hops, so it will be very bitter but not a lot of hop character like an IPA should have. I would do a bittering addition with just the warrior at 60, maybe bump it up to an oz, then do at least 6 oz of cascade plus zythos at 15 min to 0 and dry hop with another 3-4 oz.
