Liquid skills is absolutely top notch. Bio Bio is also very cool. Although we didn't actually stay there, we went through their camp as a take out one day and it looked awesome.
I know Nate, but haven't used his outfit. Nate is a solid dude and should be considered for sure.
But bottom line it's a long way from home, the weather can be harsh and if I was to do it again (which I plan to), I would again go for some creature comforts in mind. Nothing like a hot shower, hot tub, and meals that fill you to the brim.
You are going to have a blast!
