Also, I would increase your boil by at least a gallon. The PB2 will settle and leave a gallons worth of trub on top of what you'd usually have.
Maybe play with the yeast? I liked the London Ale, but it did give a sweeter finish.
Let me know what you come up with. This has been a huge hit, but I'm always open for suggestions. Happy Brewing!
