I hear that, and the food+clothes+little things are where the magic is. A new sleeping bag is a must for me, however, and the last remaining "big item weight savings"
I shaved 4.8 lbs on my pack alone, if I do go ahead and use the KU5200 that I purchased this last winter. I still haven't decided on this one, as my DT1 is soooo comfortable. Shaved 3.25 lbs from my sleep system, and shaved around 0.5 lb from my kill kit. I will be taking less base layers, so will save some wt. there as well. And finally, if I'm able to slip my spotter into my partners pack, that will shave almost another 4 lbs from my pack.
