You can sub 1 lb of malted wheat for 1 lb of 2-row, instead of adding carapils. The extract has some carapils in it anyway, and the C-40 should give you some of the same effect as well, if you want to leave it as is. I'd scale back the columbus, but if you want your beer enamel-strippingly bitter, 2oz is fine. I'd move the 30 minute Galaxy to 15 so you don't boil off most of what it adds. Maybe double it to 2oz as well. Now I'm jealous I don't have half a pound of Galaxy hops. Alas...
