>>2244919It's clear that if you only do stuff on relatively flat environments. It's not particularly useful.
But for climbing more than 1000m and also descending them. It's not the same thing. It is necessary if you are doing 30% slopes with 20kg on your back, like have do in this trip (pic related).
I evolve between the Swiss and French Alps for most of my outings, which implies big climbs.. I imagine you are an American living in a flat area.
