Thank you for the thoughtful recommendations, I really like most of them. A few notes:
-Bug shelter is definitely on the heavy side. I thought I'd enjoy having extra bug free space, but it hasn't worked out that way. I've figured out I really just want a bug free space to sleep in, so I'm looking at swapping the bug shelter out for a bug bivy to cut the weight in half at least. Or, as you said, only take it when needed.
-pot is titanium, but the lid is way too heavy (can double as fry pan, but I never use it for that). I think I could shave considerable weight just by making a new lid.
-DEET: I almost never use it anymore, after treating my clothes with permethrin. Good stuff. I might carry 1oz as backup.
-Stove: I've been fiddling with some MYOG alcohol stoves. They sure are light and cheap! Not sure I want to ditch the convenience of my trusty Giga Power though.
-Good call on ditching the fleece. I usually wind up wearing it or the nano puff... :) I do want to carry a lightweight long sleeve for sleeping in, but I can easily find one at half the weight of the fleece or less. Also thinking about a vest to sub for the nano puff.
-water filter: Got my eyes on the Squeeze mini when it comes out. I'm not a fan of chemical treatment.
-knife: Ah yes. Definitely could save weight here, but I really love this knife (lol). Benchmade NimCub II, 3.5" fixed blade @ 3.2oz without sheath. Keeps its edge better than anything I have ever come across, by a long shot. Extremely tough. Might be equally tough for me to part with it. I think I could make a lighter sheath though :)
-Pack: I like it but don't love it. I'm almost certain I could find a pack that is lighter, more comfortable, and transfers load better.
-Bag: I actually do like the bag a lot, but I mostly use it unzipped, as a quilt. Also, I find I'm a little warm at times, so I was thinking a 40deg quilt would be a nice substitute, and it'd be about 8oz lighter.
I'm also thinking about swapping out the large wide synmat for the regular size one. At 5'10" and 170lb I think I can squeeze onto it. :)
Thanks again for the advice! Really helps gets the gears turnin'
Edit: By going with all of Ben's above suggestions except new pack and quilt, I would save around 40oz! Nice.
