Summit Great Northern Porter Clone

Anyone have a recipe that’s close?

I got the info from their website and was thinking something like this:

10# 2-row, 1# chocolate, 1# caramel 60l - Mash at 154 for 60
1 oz northdown @ 60, 1 oz fuggle @ 15, 1 oz cascade @ 5
1056 american ale

1059 og, 44 ibu, 30 SRM, 5.7abv

Too much chocolate?

This is mostly a bump, since I am not the best person to critique a recipe. I think that a pound of chocolate might be too much. I would probably take it down to a half pound. The hops are probably pretty close.
