To be honest, I think the chocolate will take over a little. I just did a brown ale with 4 oz of Fawcett Pale Choc. - it's pretty good, but the late hops are a little overshadowed. Actually, add a few more #s of pale malt, change the C-40 to 120, add 4 oz of Victory and scratch the Munich (okay, that's quite a few changes), and it's a ringer.
But what do I know? I'm sure it would be tasty as is. You do have it pretty heavily late-hopped.
