Guthrie,
One small question, and don't take offense, but have you climbed the south side of Hood in the winter yet? It might be a good idea getting a feel for the mountain in general on the easy side during the winter before attempting the n side. As Billcoe notes, you'll be spending more time slogging through waist high snow than placing ice screw protection. I definitely recommend investing in your -20 bag and bivy as a plan b to ice screwing your way up cooper. It's just a suggestion, because when that wind hits 50 mph and the temp drops like a rock, well, you know. Anyway, I'm probably drunk already, so it's time to throw in the towel. Hood is funny. It changes directions on you.
