Wall climbing sucks, but the places it takes you are amazing. This little guy not only offers the efficiency of it's big brother the Pro Traxion, but also weighs nothing and racks almost invisibly. I like to use a pre-set ratchet system on walls so having 3 biners and 3 pulleys + cord add's some weight to my rack already on slings. But with this little guy I can significantly reduce my overall rack weight and bulk. Did I mention it can easily haul a grade VI kit 1:1 style efficiently? Yaaaa it's the bomb.
Also I dropped this thing from 600+ft and it still looks like new. Wow
