Nice ski.. nice video. snow looked good, The camera POV makes it look 15 - 20 deg slope when in fact, it is not. And thanks for the new tunes.. very David Byrne, Talking Heads-esque.
It's true, there's always a tradeoff between recreating the experience in the most realistic way possible, vs creating a video that people will actually enjoy watching. I film in 360 mode so I could theoretically use any angle for creating these videos. Adjusting the view downwards makes it look steeper, but quality suffers. Most ski videos that use this technique are borderline unwatchable.
I have no idea, but we did it as a day trip with lightweight glacier gear. The real question is, what's the minimum amount of stuff I need in order to do this safely?
