I've been using stepps exclusively since 2017 with 1 or 2 short stints of just trying new climbing sticks. Nothing beats them for an all around package. They are the best compromise of light weight/packable/safe that is out there.
Are they the lightest? No, I carry 7 so it's 7 pounds. But they pack tight and fit in the shelf of my pop up so that counters that. Once you get the hang of putting them on its second nature. I actually don't even think about it because I couldn't tell you how I do the knot anymore, I just do it. I have had a couple slip on me before but they just slide a little and you never go very far. That's usually on soft barked trees where they bit in so well. The way I do it with a knaider I always have a step above me to hold on to to pull myself up. Anyways I've praised them on here for years but I'll continue to do so
