For Dall sheep in Alaska, I carry a 80mm scope, a heavy-5 ft. tripod, 1-2 video cameras with plenty of batteries (4-5), 1 still camera, a full-sized tent, 1-extra pair of socks, a full-handled toothbrush and paste, a book, 2-trekking poles full-length pad, a long sleeping bag, a heavier than average stove. A .44 mag., bacon, cheese, (some freeze-dried food of course) sometimes a satellite phone. I find that is is all worth the extra weight... I rarely go extreme distances though. Most sheep hunts I guide average 4-5 days and 40-50 miles. There are guys who go a lot further and and hunt longer for various species, and then I suppose if I would cut some weight somewhere, but I like to eat good, sleep good, and lack for nothing. It is extra work, but to me it is very much worth it. I am able to hunt, and live better if I am comfortable.
I do not pack a GPS, or a compass (if I were in very thick, flat country I would), a saw (I pack only a hacksaw blade. It takes a while go cut the skull, but it weighs nothing.), a knife sharpener.
For what it is worth,,,,,,that is my perspective.
