I think I got the weight to a way more reasonable point, currently with a full supply of all consumables my pack weight 55lbs, thats with 14lbs or 7 days worth of food and 6L or over 12lbs of water and 2.5 pound bear can. Base weight is currently at 22lbs.
1) I have not changed my pack, as I feel the weight is reasonable as long as I am mindful of over packing.
2) I have changed my sleeping bag and shelter system to much lighter and smaller versions, I think based on others points that it will be well worth it in the long haul.
3) I also ditched the MSR filter and am going to get a sawyer squeeze. I keep the MSR stove with canister fuel as I find it easier and to be in the end, and not that much heavier than an alcohol stove, the fuel, heat reflector, pot, lid, and handle.
4) items are more accurately weighed at the moment but some are still estimated or over shots, or recommendations of how much I will need for about 4-7 days at a time.
