Lots of good advice here. The only thing I do a bit differently is leave the tent in favour of a large tent fly which I make into a lean-to, and my "stove" is a folding wind deflector with a lightweight grill over it. (I'm an old timer.) I can get away with this because I always camp in the thickest timber I can find. If I have to camp above timberline a tent and proper stove is a must. Internal "A" frame packs are the best in steep going but external frames are good in open rolling hills. Don't go lightweight on your boots and use heavy high quality socks with a pair of ultralight liners, (take an extra pair of liners). Leave your Bowie knife at home and take a one with replacement blades so you won't need a sharpener. Plan for success. Get some lessons on how to properly bone out and cape an animal. Lots of weight can be saved by bringing out only what is absolutely necessary. If there are two of you think about bringing a lightweight folding saw. Finally, it may seem superfluous but an ounce of super strong vodka mixed into your hot drink at the end of the day is a nice muscle relaxant.
My pack for 5 days comes in at about 45 lbs if I take mostly freeze dried food. I could do a little better because I always seem to have an extra butane bottle. Their are times when I minimized the freeze dried food though. I don't like to drop 2000 feet to get water supply and freeze dried food requires a lot of water. I will usually pack some water up the hill before opening day but i can't seem to carry 5 days worth of water with all my gear if I have to rehydrate all my food. In that situation my pack starts out hevier but is lighter on vertical climb to elevation because i have to fill water containers be for I leave the creek. The extra gallons of water is brutal. I can also make it 1 small butane bottle when i have food that doesnt require boiling water.that system seams to work for me. If there is a spring on the mountain I'll take more freeze dried food.
