+1 on the zip ties and duct tape. I'd also add a good compass. For the dental floss and other cordage try substituting a spool of 50# woven fishing line, like spyderwire, . Use it for tying things together, sewing up rips, making snares, guying out poncho or tarp shelter, etc. Even though you plan on daylight only, I'd put in a light of some kind, murphy's law hasn't been repealed yet.
