You might consider dropping the H.M. down to 1 lb.... the time that I used 2 lb was a little cloyingly sweet. It imparts a LOT of mouthfeel too. It's really good, tho, I dig it! If you have a spare pound of pale malt or Vienna or something, that would replace it well. The C-120 will impart raisiny tones, if you're looking for a caramelly, toffee-y taste you would be more suited towards C-60 or so....
But I think the hop schedule looks just fine. SHould be tasty, but could possibly need a couple months to really hit its prime.
