I'm with NB...Malt bill is fine except that the Maris and Pale are totally redundant. I use good Pilsner in a split with Maris or with my local maltster's pale malt, but no reason to split that way. Also, I personally prefer Biscuit or Victory in place of the Crystal, though I've done nearly exactly that same recipe using Pilsner, Pale, Munich and C-40.
I would say that unless you're just trying to save money on hops, using up IBUs at 60 defeats the purpose. I'd put no more than 1/3 of the IBUs into the 60 minute addition and load up the late additions more, as Boomer has done with his. That's where Citra really shines.
