That looks good. Pushing 10% with the raost/chocolate malts, but the extra crystal and dextrin will balance it. I've got waaay too many good porter recipes to try, and now I need to add this one to the list...

I figured that a gravity of this range could handle the roast and as you point out the crystals will balance it. Also the mash temperature is high and the hopping isn't out of the world, so...
