So I brewed something similar to this this last weekend. I ended up using 6 oz pecans, and toasted them dark in the oven as you suggested. I also added a cup of molasses. I didn't have the glacier hops so I used some Nugget instead. Otherwise, I used the exact same grain bill.
This was my maiden voyage for my brutus 10 system I just finished, so I'm excited to see how it comes out. Had major activity within four hours...
