I would also carry a short and a long coyote-coloured Z-Rest, in case of failure of your Neoair.

I would most definitely carry alloy crampons and maybe a super light ice axe, but, the crampons plus two BD hiking poles should get you through anything you might encounter.

Spotter.....find out for sure if your guide will have one but do carry a highend bino, I have Zeiss and Leica, Swaros are great as well.

Northern BC, wish it were still like it was when I first lived alone in the mountains there more than 40 years ago.
