Right off the bat, I can't remember what hops are in there. I'll be at the brewery tomorrow, and I'll try to remember to ask.
You can also email the brewery (firstname.lastname@example.org), and they'll probably tell you. You can also call DeFalco's or talk with them if you go there for ingredients. Their sweet stout kit uses Target (or Northdown) and Willamettes. Something tells me that's not a coincidence, especially since the two guys that designed the original Saint Arnold Stout recipe are Foam Rangers.
You might be surprised about that FG. It does sound high, but there are a lot of unfermentables in that recipe.
Also keep in mind that the original St. A stout was more of a very robust porter, bordering on a sweet stout. That's what the guys won the first Bag Batch Brew Bash with, according to them.
