For the most part, I like it a lot. My biggest hang-up is using Fuggles early to bitter. It really is more of a finishing hop and seems like a waste to use strictly for IBU's. Adding it at 45 minutes, I don't think you will get much, if any, of it's British earthiness coming through. I would either bitter entirely with something else, like Magnum or Nugget for example, or just make it a Cluster only beer. No better way to find out what a hop brings to the table then using it exclusively.
On a more nit-picky note, why both C-malts? Can you really notice a difference as opposed to just using one?
