@Justin: great tips. You know your bushcraft well.
@Ken: good ideas, thanks.
-The 2 oz map weight might be a little high, but it accounts for the detailed maps and sometimes route descriptions I might print for the areas with sketchy trails or for bushwhacking.
-The small lights, backup compass and backup sunglasses total around 0.5 oz and don't add any perceived clutter, so they're worth the weight to me.
-Good idea on the floss. Repair kit contains needle, thread, unwaxed floss, duct tape, tyvek tape, cable ties, downmat patches, superglue, few other things
-I don't really need to melt snow, as there are plenty of flowing creeks and streams. It's one of those fun, enjoyable elements of winter camping which I enjoy doing at least once on a winter trip, especially the first of the season. If I ditched the Steripen, I'd carry more water.
-I've used the stove on one trip which was mildly damp, but I've also done many fires in wet and snowy conditions. I might just ditch the stove and use an open fire, as prepping the wood for the stove is sometimes more work than building a small cooking fire because it has to be cut to relatively precise lengths. I like the idea of not carrying a stove at all.
I'm starting to think about using just a bivy bag more. Waking up to cold rain in my face while sleeping in my duct-taped trash bag bivy is a very pleasant memory from my teens...
