1L smartwater bottles instead of the Nalgenes.
definitely a lighter tent.. that is one hell of an anchor
many lighter sleeping bags or quilts.. depends what you do / where you go.
I like the dragonfly but not for backpacking.. Canister stove or alcohol cat stove so much lighter.
trail shoes instead of boots.
Skip the Camp Suds.. water and the brillo pad or just your spoon works fine. even "biodegradable" soap isn't great.
skip the trowel.. use a stick, stake, trekking pole

buff, bandana, camp towel... pick 1.. maybe 2
mini bic lighter and a packet of bar matches for backup in a ziplock. vs waterproof.
