I'm rather new to this site, but already I wish I had found it earlier. I'm not new to hiking (nor do I claim to be an expert), but I'm still learning in regards to UL (and SUL?). I want to cut my weight even further and I don't mind sacrificing comfort. How should I proceed?
I don't know if you are all familiar with the website/program called "gear grams". I'll present my list that way:

I already know that I need a new sleeping bag. I'm trying to figure out the best way to turn the one listed into a quilt. I don't have a lot of money available.
I bought the Bivy two years ago and have yet to actually use it – don't worry, it doesn't sit idly in my pack. I have only taken it on one previous trip. I realized on my last trip that I didn't want to be restricted to cowboy camping or huts (all of my trips are on the AT). That is also where the poncho/tarp comes into play. This is bad, but I don't even know what type of material the poncho is. It isn't too heavy and I know it's certainly waterproof – I see it as a temporary solution. Like I've said, I've never used this system. The general idea is fairly simple:

Please tell me what I should do differently (because this is pretty unrefined). Before adding the tarp and bivy, I didn't carry a shelter and I carried a Golite Tumalo 2.5 layer Pertex Jacket (10oz) for rain protection.
If you're wondering where my insulation layer is, I haven't listed one because this specific trip is planned for the next couple of weeks. I don't expect Harper's Ferry to be freezing in early September (although I could be wrong). For colder trips, I carry a Golite Roan Plateau (16oz 800 fill down jacket, hoodless) – that's going to limit me eventually.
About the running shoes, convince me otherwise.
I've come a long way in terms of weight. Tear my list to shreds, be brutal. I want to improve more. Thanks in advance.
