    Yes, it is a shackle. That is the only component on Nicks concept sling that has been the cause of concern. I was just pointing out that shackles of that type are strong, have a proven track record and have ratings just like steel shackles. I will be interested in how things work out in load testing.

    It is interesting that a major company like Yale Cordage has no problem using and certifying this technology. I wonder how many lawsuits they have endured due to catastrophic failures.

    I still like that there is nothing to drop or lose and the whole thing is soft. Lack of trust in its reliability might be perpetuated by lack of field experience with this particular sling. Many things look daft until you try them.

    Well, you could be right, Reg, I have no idea if Nicks sling will work but the soft shackle has a history of use going back hundreds of years. They have successful held some really big shit.

    So are you thinking that his sling is not strong enough or that it is functionality less secure?

    https://www.allaboutbirds.org/guide/Northern_Harrier/id Yup, Stig is right. Either a northern harrier/marsh hawk or a rough legged hawk would be the most likely. The harriers have an unusual flight style, usually close to the ground with a quick twist and spin when they spot something edible.

Feed stock and processing methods will produce widely different products. There are many papers available on this. I used this one as an example merely for its simplicity and the use of oak in the feed stock.

    I think that what Kong is trying to depict is that the cam is not a pulley surface and to not use it as such. Clearly, with it against the rigging plate it is not being used as a pulley but merely as a rope grab. I could be wrong, but that is what it looks like to me.

    Good catch, Brocky. The CT roll n lock has no such limitations. One of Richard Mumfords videos goes into detail on the differences between the two. That said, having the Kong against the rigging plate does seem to entirely change the load dynamics.

    DMc replied to a thread Adjustable rope bridge in Gear Forum
    That should work fine. When I was climbing in the TreeMotion I used the same setup as Richard, with the CT roll n lock, for awhile. Though it worked well I found that I just didn't use it very often, so when I switched to the MCRS I left it off. I have heard concerns that having a rope grab in that location could conceivably damage the rope sheath if it were shock loaded. Doesn't seem likely but something to think about I guess.

    I agree, Stephen. That was a simple and effective demonstration on the usefulness of the hook. Nice smooth technique also.

    The Captain is a cool tool. The shape and balance are just right. It works best with a very light weight rope as comes with the kit. Unfortunately, the Gri Gri does not work well with Sirius Reep Schnur but the Trango Cinch does. For a haul back system, the Petzl Rollclip paired with a CT Roll-n-Lock works great. <iframe width="560" height="315" src="https://www.youtube.com/embed/IvCkrFlq1_g" frameborder="0" allowfullscreen></iframe>

    Really? Have you used a properly functioning knee and foot ascender combined with a chest harness tending a multicender? No comparison and no going back for me.
