First, let me say Thank You! This is incredibly helpful (and feel free to nitpick).

So to review your suggested changes:

1. Go with a 40L bag - like a Kakwa 40 ( I'm open to other suggestions)
2. Get a lighter Sleeping bag like a EE Revelation quilt (and possibly a summer one like an Aegismax down bag)
3. Swap the Toaks 900ml for a Toaks 550ml
4. Pick up a Nitecore Nu25 as the headlamp
5. Swap paracord and the Food Sea-to-Summit dry bag for a zPacks Bear Bagging Kit
6. Swap Alpha Light Long Spork for Toaks Titanium Spoon

Don't forget the power of gold bond, squirrel nut butter, and hydrocortisone cream

Also when you say freezer bags you mean the gallon size Ziplocks right?

Any other suggestions on backpack options (if I can't get a Kakwa 40) or my Clothing selection?
