I mulled over using honey instead of brown sugar, too. Any honey beer I've tried had a bit of a floral quality to them. I don't know if that would be appropriate for this beer. Plus, I've never brewed with brown sugar, and think it might be interesting.
I'm also inclined to stick with the Edinburg yeast, for reasons we discussed earlier. I think the 007 might make a beer this big a little too hot.
Just my opinion....I'm willing to go with concensus!
Also, I'm really digging that grain bill. I'm almost inclined to suggest swapping the 30 min addition with .5-.75oz of Chinook (what ever would keep the IBU's about the same). Many people find Chinooks a bit too potent, though.
Also, here's another suggestion: Let's all try to use the same recipe. That is, the same basic ingredients. But I say give leeway to tweak the amounts to one's taste, i.e. hop amounts, base malt, etc. Some might want theirs bigger or milder, more or less bitter, and so on. Agreed?
