BW, I use a WM Versalite. Love that bag for fall elk hunting. Light, packable, and warm for Oct/Nov hunting.

If you're not interested in dropping that kind of coin, right now a lot of the very good Marmot bags are on sale. I'd look at the Marmot Helium. Many places right now are giving 20% coupons for labor day. You should be able to pick up a Helium for around $320.

No experience with the new treated downs, but I've never needed it either.
