The only thing I can add is for the sore knee people coming down steep hills. Try this technique for steep hills. Looks silly but I tried it on a 800m descent over 2.3kms with a through pack (2620' over 1.42 miles), quite steep, and my knees were fine at the bottom. Of course my quads were killing me as they were taking all the strain. If you practice it you can prolong your years of bushwalking, and your muscles get used to it. https://www.youtube.com/watch?v=FL8j_x5B4Nc Have a look at some of his other videos, they specialise in getting people ready for climbing/trekking. Some good advice in there.
