Happy you guys made it down in one piece. That was quite the epic. Good to see the old guys giving you some solid advice here and I hope you take it and maybe throttle down the objectives to more moderate terrain until you have a good base of knowledge and experience in the mountains. As an old guy, I remember Marc Andre on here many years ago doing moderate objectives around Vancouver, posting TR's and being completely stoked to get advice. You should try it. The harder stuff will come with time, or you'll run out of time with horrible results. I've been on here long enough to see too many people get in over their heads and never come back. Don't let that be you. Climbing those kind of routes in winter adds another level of complexity. Try some longer summer alpine routes to get "The Dance" worked out.
And a space blanket lives in every one of my packs without leaving. Even better, a lightweight bivy bag or tarp. Canadian Rockies guides don't climb without one. Found that out the hard way after our own epic up there, and I was seasoned even back then!
Cheers and good luck!
