Hey dude, looks great, just a few little things:
MSR Pot grip (-1.1oz.)- Seems you could just let the pot cool for a couple seconds and use your bandana.
Timex watch (- ? oz.)- You have a smartphone and a watch, seems like the watch becomes a duplicate item possibly? If you're going to bring it you might as well wear it (you mentioned w/o strap) I think instead of possibly losing it or having it somewhere in/on the pack.
Darn Tough socks (-2.5oz.)- Could you do with only 2 pairs of socks and cycle them daily?
Journal/Pen (-4.4oz.)- I've never done the AT and have no idea how frequent your resupply/town stops will be along your chosen section but could you possibly use your Motorola smartphone to log your journal entries in the evenings?
Brooks Running shorts (-3.16oz.)- Sorta redundant having 2 pairs, as one pair of running shorts will dry out in a matter of minutes if they get saturated and really don't hold any moisture, although I'm very familiar with how stinky they get but to each his own.
Hefty Compactor Sac (-1.3oz.)- I completely understand not wanting to get your quilt wet, however, you already have most your gear inside a Hefty Compactor bag INSIDE another bag, your pack. I would think using caution and not storing your alcohol inside your pack and placing all drinking water in your side pockets or shoulder strap would eliminate most risk for compromising your quilt. My vote is don't bring the extra Hefty bag for just your quilt. If you do decide to bring the extra Hefty bag for your quilt you might as get rid of a stuff sac (- 1.1 oz.) and just throw all your carried clothes inside the Hefty bag w/ the quilt.
Good luck with your AT section. Cheers.
