Bornagain and Guru probably have the best systems so far. I have researched and experimented a lot. My favorite is a Kifaru pack, possibly with cargo chair, and a simple, lightweight stand like a Loc-On Limit or Windwalker, with Lone Wolf sticks. This will give you maximum adaptability for different hunting situations, as well as an extremely comfortable suspension, not to mention industry leading quality on all counts. I have used this system for everything from a morning hunt to an 80 lb load for a week in the backcountry.
