Porter recipe opinions

I'm making a clone recipe, even though I'm generally against clones, but this is actually because the brewery that makes the beer doesn't distribute to where I live. It's a porter by Georgetown Brewery (http://georgetownbeer.com/products#porter). Given the information provided by Georgetown for "beer geeks", this is what I've come up with:

3.5 gallon batch
1.072 OG
1.024 FG
6.24% ABV
IBU 39.22

4 lb American - Pale 2-Row
2 lb German - Munich Light
2 lb American - Caramel / Crystal 60L
1 lb American - Chocolate
8 oz American - Black Malt
8 oz American - Roasted Barley
4 oz Flaked Oats

0.5 oz Centennial (60 min)
0.5 oz Northern Brewer (20 min)
0.25 oz Northern Brewer (10 min)
0.25 oz Northern Brewer (1 min)

Does this look alright? I thought a lb of Chocolate malt was a lot but the website says lots of chocolate malt and I do remember that taste in the beer I had. What would you change?

2 lbs 350+ lov roasted grains in a small batch is a LOT, and I'm a roast fanatic.

Thanks for the input! Does this look better? http://www.brewersfriend.com/homebrew/recipe/view/80315/darkhawk-porter

i like the changed one a lot more. i tend to prefer a darker crystal in my porters, but i think your recipe will turn out wonderfully. let us know how that much munich works out, please.
