I think I'm done tinkering (at least for the time being) with my kit!

I've got the list set up to account for change in season (for example, added in the additional ounces for my cold sleeping bag and seasonal clothing) and luxury items that I may decide to swap in/out depending on the trip.
There are a couple things that say 0oz (I went with oz not grams) because I rounded things up or down, so it likely evens out in the end.
It's 14lb if I carry all of my cold weather and every luxury item listed (which I've never done... for example, I've only ever brought the chair on leisurely summer trips with a "base camp") and just below 10lb if I carry my summer kit and no luxury items.
There are certainly a couple things I could lighten up (aren't there always), but this strikes a nice balance between weight and comfort for me.
Add in 2L of water (4.5 lbs) and a generous 3-4 days of food (6-7 lbs for what I consume during that time usually even is extra), and I'm about 25lbs at my absolute heaviest (I'm about 100lbs, 5', so I don't want to push those numbers).
