If you mean "most hop forward" I would say Storm King and Old Raspy (not a bad thing, I totally love them). Most RIS's are "hoppy" by definition (i.e. high IBU's) to balance the grain bill made to use them. Not uncommon to have a 70-90 IBU RIS with lots of rich malty "stout-like" goodness. I guess it depends if you prefer a balanced RIS or lots of late kettle hop forward RIS's. I like them both depending on what I'm looking for.
