Thanks for the feedback guys. I am going with the 2000. I wish I had the proper yeast, but I have a bunch of coworkers who will be joining me for brew day this weekend, and I can't really move the date. As long as it tastes like a good "autumn" beer, I don't care too much about it truly being an O-fest. By the way, here is my recipe:
4 lbs Vienna
3 lbs Munich
2.5 lbs Pilsner
.5 lb Carapils
.5 lb Caramunich
.25 lb Melanoidin
1.5 oz Hallertauer Mittelfrueh 4% (60 min)
0.5 oz. Hallertauer Mittelfrueh 4% (20 min)
single infusion @153, batch sparge
