RE: Backpack List....OK??
If you pack well 3500 will suffice, most people I know prefer 4500 - 5000. If I am hunting game larger than deer I carry a bigger pack just because I can fit more meat into it at one time.
If you have not bought a rest think about one of the Big Agnes Insulated Air Core pads. They get you a full 2.5 inches off the ground, roll up smaller than the Therma rests and weigh less too.
