Boy if I had to open my PSK for the items you suggested I would have turned around and headed back to civilization.
You got to remember when packing and weighing your pack to pack backup gear just in case. Plus you should have a PSK for survival reasons. Before I set out I inventory everything in the kits I'm bringing along, replace anything thats old and rapackage it.
If I were you I would start with a list of items you should bring and then decide where to cut superflous items to save weight.
