I'll throw out a few minor observations. I know many of my comments = spending more money.
I "upgraded" from "standard pack cover" like you have listed to a dyneema one about 8 years ago...shaves some weight.
I never use a knife/leatherman...but I suppose could be important to have.
I never use campsuds or soap. (I generally avoid cooking in my pot so I don't have to clean up. I repackage and use freezer bags.)
I got a lightweight clip on flashlight thing (rovyvon?). Only tried on one trip. So far so good.
I'm not a fan of the weight of jetboils, but I hear they are great. Could get a lighter weight stove.
I've found some
camp shoes that are lighter. 6.14 oz for size 8.
Could find a smaller bottle of DEET?
I've never offered up advice on a shake down so hopefully I wasn't lame about my comments.
