I am new to lightweight backpacking and am yet to even take my first trip. I have done some traditional backpacking in the past–mostly 2-3 night trips. I have already returned most all of my traditional gear for lightweight options but I think there is more that I can do.
Where I will be hiking: primarily in the Colorado Rockies
Length: 1-7 day trips (possibly longer with resupplys)
Who do I hike with: I will be hiking in a group of 2-4 for most trips but do plan to do some solo trips as well
Here is screen shot of my list. Let me know if there is a better way to provide visibility to an Excel file on here. I cant find a way to attach a file (2nd post..)

The 2nd column is for Mandatory or Optional. X=Mandatory and O=Optional.
My total Mandatory weight is at 12.46lbs and total Mandatory + Optional is 15.06 (pack not included because I haven't purchased one yet).
What can I do here to drop my weight further? Which things are absolutely dumb that I carry? I am new to this and have already cut my pack weight in half from last year.
Thank you
