I have both the Superday, and the 2200. For a backpack/three day size pack the Badlands packs are very good. The Superday is just about perfect for a daypack, with all kids of pockets to put rangefinders, gps, knives, extra clothes, water, food, etc.
If you want a bigger ruck, for mountian hunting, backpacking, etc., then there's really only two choices... Mysteryranch, and Kifaru. Both excellent.
