I followed Nail's recipe to the T and ended up with a fantastic beer that's just now reaching it's prime (1 month after bottling). It's a little harsh after two weeks in the bottle but give it a few extra weeks after it carbs and it will really shine. Terrific hop aroma and flavor (love Amarillo!) and head retention is great. I think I actually prefer this to real Gumballhead (but the similarity is REALLY close). I would definitely brew this again, but maybe as a summer beer.
