Yooper, I just took a look at the AGDeadGuy.bsm you posted on page 1. That differs slightly from your original AG recipe (page 1) and the recipe on Brewmasterswarehouse.
I went with:
10 lbs Crisp Maris Otter
1 lbs Caramel Munich
1 lbs Weyermann Munich Type II
8 oz Briess 2 Row Caramel 40
Your Beersmith recipe calls for an additional two pounds of Maris Otter and .5 gallons as the batch size.
Will the missing two pounds of Maris Otter make difference?
My notes say that my efficiency improved so I started using less grain to get to the same OG. If your efficiency is 75% or so, the recipe on Brewmaster's is correct.
