I think a lot of the decisions get made out of comfort, or familiarity with a certain way of doing things. And a lot of people think along the lines of "what am I supposed to take" rather than "what works for how I do things" Its one of the problems with following an expert. Cody does this, Les does that, Mors does a third thing, Ray is carving a pizza paddle out of a redwood. Without looking deeper into why they are thinking along that line, and what's brought them to that method, you don't have the full story. It will be interesting next ep to see what the guys who call themselves instructors do.
Most people don't start their planning from when things have gone wrong. They start with "It will be cold, I will take a sleeping bag" not "When I get soaking wet and its cold, what sleeping bag, that is also soaked, will do the best to keep me warm."
For my money if I knew I'd be relying heavily on fire I'd have a lot of canvas, wool, and synthetic insulation. But I'd also not plan to move far or fast. If I had to cover terrain, then its tech fabrics all the way, and heat would be provided by a very heavy calorie intake. When I camp, I try to keep as light as possible, but that means some compromises with my gear that I know I'll have to think about if things start going badly.
I think Larry is going to get the better of himself. He lets frustration get into his thinking. Frustration with himself, and with his situation. The fact that he was down in that little muddy puddle, just sort of baffles me.
But I'm not out there, and am very unlikely to be. So what do I know?
