Sleeping:
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.
