Not exactly what you are looking for but I brew a Sorachi Ace Saison that is very good. I use magnum for bittering (60 minutes 17 IBU) Sorachi at 20 minutes (15 IBU) Sorachi at flame out. This beer is 5.8% with 32 IBU's. I would think doing something similar with an APA grain bill and upping the IBU's along with dry hoping would be pretty good. Have you used Sorachi Ace before?
