I would stick with a totally static system ,no dynamic elements such as your dynamic rope anchor, as this can lead to the stretch that allows the part of the system that runs over the edge to rub, and that friction causing wear and tear damage, edge protectors or rope protectors are critical, you don't mention using any ?
And I also like the non toothed rope grabs for this activity, e.g. petzle micro or rescue senders, these are great, and have been copied by Ferno, check out their site, good stuff. |
