Shelter: Yeah, I'm definitely thinking of switching out the tent, that would be the main thing. Maybe a Big Sky Soul or Hexamid.
Hydration: I kinda went back and fourth on this one. A 1L Gatorade bottle weighs 1.8oz on my scale, so three of these would be 5.4oz, vs 6oz for the 3L BigZip. The lightest recyclable bottles I can find are 1 Liter Smartwater Bottles. These each weigh 1.3 oz. So three of these would equal 3.9oz. The Platypus BigZip 3L is 6 oz, so I would save 2 oz right there, but lose the ability to drink and walk. The regular Platypus 3L is 3.8oz, but I think it would be too much trouble to refill. But between a regular Platypus and three Smartwater bottles I don't see why I would go with the bottles?
The filter, I just don't like to wait to have to drink! But yeah, I can see how I might not absolutely need it. I could at least leave out the water pouch, straw, and syringe (just use a water bottle to clean).
Cooking System: I took your advice and checked out the Caldera Cooking System. I didn't have time to go through them all but I checked out the "Caldera Sidewinder System", which includes the cone, the stove, the pot, the lid, and the bottle. It came out to 13.75 oz, which is 2.75 more than the Jetboil. The fuel weight is kinda the deciding thing, I'm not sure how much alcohol would be equal to a 7oz canister. If there is a less heavy bundle please let me know, but I'll keep looking through it.
Other: The umbrella, I might send back or ahead if I feel it's not worth the weight. There are lighter options too, but not hands-free.
The charger and batteries I would be using for the headlamp and to recharge my phone/camera/musicplayer/gps on the trail. Probably don't need four, yeah...except that I use an electronic cigarette X). Didn't want to let that one slip, that son-of-a-bitch is heavy. Hopefully I can quit by next year!
Thanks for your time.
