I used 15% flaked rye in my latest Rye PA (all grain) batch. There is a very similar taste on the back end to the ruthless rye, which I assume is the rye. I didn't use any crazy hops, just cascade and galena for a citrusy/floral bite. I know I'm being bias, but after my non-dry hopped and non-carbonated taste test, this might be the greatest beer I've ever made/consumed.
I should also mention that I think mine is a little sweeter than the ruthless, and I attribute that to the honey malt I used.
