Dig high camp in at 11,000' and you should be sheltered from the icefall. Also a good camp at 13,000' after the little bit of technical climbing. Realistically, the Kautz can be done in a single push if you're fit and acclimatized. If not, then it's a 2 day climb. Descending the route only makes sense to me if you're going to spend an extra night at high camp after summitting on a three or four day climb. Otherwise, going lighter, moving faster, and carrying over to the DC is a simple descent.
