Black IPA Recipe - Input Please

[elmito]

So I bought the following ingredients from a Local Brew Shop, it was based on the NorthernBrewer All Grain Black IPA. http://www.northernbrewer.com/documentation/allgrain/AG-BlackIPA.pdf

The local shop didn't have everything in the recipe, so we changed:

- carafa III to carafa I
- Caramel 80L to Caramel 90 and 60 (he said it should equal to about the same)
- we also cut out a few lbs of 2 Row and substituted Light Malt Extract so all the grain would fit into my 10 Gallon Mash Tun.
- he also suggested I steep the carafa and chocolate rather than mash it.

So, what do you "experts" think? Any input would be greatly appreciated, I plan to brew in about 4 hours when the sun isn't as deadly, Miami weather is a b*tch.
