Nix 1/2 zip fleece, use the Capilene 2 L/S as a midlayer instead
Nix Shirt 3
Nix the spare underwear
Nix the sandals, Roclite 295's are just as comfy and dry fast
Add in a rain jacket
Saved: 22oz, take away 6-7oz for a light rain shell
Nix the drybag for clothing, trash compactor bag is fine (saves 1.1 oz)
Nix the drybag for sleeping gear, trash compactor bag is fine (saves 1.1 oz)
Nix the goosefeat pillow stuff sack and just use the Exped. You don't need a pillow cover when you are wearing a hat and a hood (saves 1.9 oz)
That's 20 oz or so total saved once you add back in a rain jacket. There easily can be several consecutive days of thunderstorms in July, and with a 2 week trip you can't plan around the forecast. If you do go without a raincoat, be prepared to hunker down under your tarp for an extended period of time which might put you behind schedule.
You have a lot of extra clothing in there. Keep in mind it's really easy to wash clothing on the trail. Every 1-2 days I go swimming in a lake which washes out the underwear, and you can easily rinse out a shirt and have it be dry in 20-30 minutes if the weather is good. If you use your Capilene 2 L/S as a midlayer then you don't even have to wait for the first shirt to dry.
