I think the starters worked out. I decanted and fed them each a quart of starter. By the time I pitched tonight they were very lively, and smelled like belgian heaven.
I ended up altering my hop plan just slightly. I went with magnum bittering on both, but then one got 2 oz Hallertau Mittelfruh and the other got an ounce of domestic Hallertau. The one with mittelfruh will get two more ounces dry hopped, and the domestic will get an ounce of domestic dry hop. I gotta say though, that 3724 smelled so good I almost wish I hadn't hopped at all.
They're all oxygenated and pitched, sitting at 65º for the night. Then I'm going up 5º per day to 90º.
