Nick: all good suggestions.
Pack: The Z1 is just what I have here. I realize it is probably volume overkill, but I cannot justify buying (another) pack. I believe a Zilch would work fine. I need the belt and sternum strap because of the bouncing running causes.
Pack liner: I may make a liner custom fitted to the pack out of cuben fiber. See the MYOG forum and the cuben fiber stuff sack discussion.
Foam pad: I am looking at the weight of a cut Ridgerest and a GG pad. Good suggestion.
Stakes: This is an issue with versatility. I have some shepard stakes, but prefer my nails for better and more reliable holding power.
Bivy: I do not like the Soul Lite because of the lack of a mesh window. If I am getting a bivy it will be for bug, wind and splatter protection. Also, I worry about the bottom of a bivy being shredded by the ground, regardless of what I camp on. If I use it, I would be tempted to use a thin strip of Tyvek for abrasion purposes. It is cheaper to replace tyvek than the bivy bottom. I have been looking at the MLD Superlight and TiGoat Ptarmigan. I have a problem spending twice the amount of a similar product when the weight savings is ~2 oz.
BPL Merino: I'm waiting on the next production run and looking at cost and warmth v. Cap 1. I will be running (or at least hiking very hard) for some of these hikes, so it must not be too warm. I have an R1 Hoody, so I understand the versatility.
Windshirt: probably not needed except during light spray and rain. I would rather not run outside of my tarp at night to pee without some protection.
Windpants: dropped pending testing; added Cap 1 bottoms in their place (pending testing, also).
Sunglasses: Staying via preference.
Digital Camera: again, it is what I have. I considered leaving it back, but the pictures would be invaluable.
Poles: I'm looking into a pole set from GG; aluminum for $24. The extra cost for CF plus the track record from Fibraflex makes me shy away from them.
Thanks for the suggestions.
