The first thing you need to do is narrow down your clothes selection
Why do you have a rain jacket and poncho? If you are using the poncho as rain gear, a windshirt might be a better choice here. (-9oz $~60.00)
You have 3 shirts! Drop one and keep one for hiking and one for sleeping (-5oz $0.00)
Pants and Shorts? Plus you have baselayer pants? I would keep the shorts for hiking and the baselayer bottoms for sleeping/wearing under shorts when it is cold in true thru hiker fashion! (-8oz $0.00)
Drop the dress! Raingear is what people wear while doing laundry in towns. You don’t want to lug half a pound over mountains while hiking 98% of the time just so you can have it the 2% of time you are in towns. (-8oz $0.00)
Now for the big 4
A lighter pack would help you out. You could sell your current pack to help finance it? Everyone is different so I am not going to suggest anything specific, but for long distance hiking I would think that something between 24-32oz ought to be plenty.
You bag isn’t terrible, but why are you anti down. Down is the best insulation on the planet and even in the humid and wet east is esaly used. People who talk about the wet down thing are missing two points 1.) If your bag gets wet you have done something crazy wrong, ie you have bigger problems, why don’t you fix the reason your bag got wet in the first place, and 2.) They have obviously never spend a night is a soaked synthetic bag either, because they suck almost as bad as down when wet. Not quite as bad, but close.
Your pad is a good choice if you can’t sleep on CC foam.
That isn’t a whole lot for shelter. A Gatewood Cape would offer a lot more protection for a minimal weight gain and still serve as raingear.
I assume you mean the MSR Windpro? That is way too much stove for the AT in the summer. If you really want to stay with a canister stove I would look into the Snow Peak Lightmax or similar. I would recommend a alcohol stove however as they are bulletproof and much easier/cheaper to find fuel for. Personally I like a Caldera Cone which saves you quite a bit of weight. (-3oz $30.00)
Drop the Fuel Canister for a lightweight Alcohol Bottle. A full fuel canister weighs more than 5oz BTW. It is more like 8. (-4oz $5.00)
I would skip the scrubber cloth as it will be nasty after the first use or two. Fingers work surprisingly well.
That is way too much for a solo pot. If you are on a budget look at the 3.8oz Anti Gravity Gear 3 cup pot. Are you really going to use a pan and a pot? Really? (-2oz $10.00)
Drop the Trowel and use your poles or heel. (-5oz $0.00)
Why so much water storage? You don’t need more than 2 liters. (-4oz $0.00)
Drop the pack cover and get a trash compactor bag as a pack liner. It works A LOT better, pack covers do not work! (-2oz $5.00)
