Nice gear list!
Like Erik said, I'm wondering what that 100ft of cord is for? Bear bagging should only require ~50ft
Maybe look into a lighter pad, 25oz for that pad is pretty heavy. Check out the Neoair's
Curious how you arrived at 46oz for the Quarter Dome. Thats the same tent I use for all my non solo trips, and mine weighs 63oz with titanium stakes, without the stuff sacks. So if you were splitting it in two that'd be 92oz, which is 2lbs heavier than what I'd expect.
