Thanks Greg. Very useful.
Rain jacket: I think I am conditioned to have in my gear list as I live in NW. During my last year's Tanner Escalante New Hance hike I used the jacket for all of 5 minutes. Will add a poncho and skip the jacket.
Soap: is not allowed in the backcountry in Grand Canyon. I take a half filled bottle of sanitizer on most hike and will do the same.
Good point on bags and sacks.
Good point on pool shoes. I hate the "volume" of Crocs and pool shoes might do the trick.
I am thinking about skipping Patagonia Nano Puff jacket and just taking the Montbell down parka. I think it will be adequate.
Tent: I chose Huba for this trip. I used a Sublite last time and experienced some very high winds one of the nights; it sounded like a freight train! The tent survived it but I was up all night concerned that one of the connects will become loose and the tent will collapse. Don't want a repeat, but chance of a repeat are slim, so I might go with the Sublite.
I will skip the Nalgene. Again, habit and unexplainable lack of trust on bladder. Will take my MSR bladder. I think I will be better hydrated with it.
