Decided to lose the liquid fuel stove and transition to a natural fuel stove (Zip Stove). Saved nearly a pound on the stove, and no longer need to carry fuel. Upgraded from traditional mummy bag to a Nunatak sleeping quilt (a la Ray Jardine). Saved about a half pound, but spent nearly $500. Upgraded from my Eureka! tent to a Stephenson's-Warmlite. Didn't really save any weight here, but the tent is extraordinary. My arguably four season setup now weighs less than 20 pounds. I am still carrying my solar system (panel, charger, batteries), and electronics suite (GPS, PDA, camera) so I suppose those really aren't necessary.
