Hi Jacob,
Looks pretty good so far–here's a few thoughts:
It looks like you're using quite a few stuff sacks. My preference is for one large (and waterproof) pack liner, into which goes down bag, puffy insulation, sleep clothes, etc–basically, anything that has to stay dry. In the past, I've used a trash compactor bag (2.2 oz); now I use the Schnozzel pump bag for my air mat, which weighs the same and has a dry bag closure. Apart from that, I use one stuff sack for my shelter, which becomes the bear bag for hanging food when I make camp.
Advantage of doing this is a bit of weight savings, but more important, packing is simpler and packed items fill out the pack better, compressing and expanding as I go through consumables.
Regarding your pack: when you're ready to replace it, you might consider if you really need that much volume. I manage just fine with around 30L for trips up to four or five days.
If a poncho for rain gear is your thing, I've heard the Golite works pretty well. There are WPB jackets that are lighter.
I like carrying a pair of light gloves no matter what temps I expect–they're a good multi-use item. But I don't hike in Florida.
Some of your listed weights seem a bit low. E.g., unless you cut it way down, a heavy trash bag (compactor or contractor weight) will be a couple ounces, rather than one. And 0.1 oz isn't much map–about 1/2 a sheet of 8.5 x 11 paper, on my scale. If you hike in familiar areas with clear trails, you might don't need more than that. If I actually have to navigate, I'd prefer a USGS 1:24,000 quad (~1.2 oz). Bonus with the USGS map is the back side is blank, for trip notes, journal, etc. Of course, printing your own maps is an option.
Finally, I've backpacked the last couple years in Trail Gloves and like them, but find I want a bit more cushion for rough trails and long days. I've been trying out a pair of Ascend Gloves–still zero drop, but 6mm of cushion instead of 2mm. Better rock protection in the mid foot. Similar-looking tread, but the Ascend Glove feels significantly more aggressive and grippy, esp. on rock. Downside is it tends to pick up bits of gravel. And neither shoe is great on wet, slick surfaces. Footwear choice is obviously highly personal, but I think I'll be switching to the Ascend Glove for hikes over 12-15 miles per day.
