    This is not an instructable. It is an Advertisement.

    Is there somewhere I can get updates on this or other awesome ideas you're coming up with? I am pretty excited to see how this turns out.

    I have been using the rope wrench for the past 2 years. Would you say the feel is comparible overall?

    Yes, there is much less friction on ascent. The descent is not as intuitive as a hitch but easily figured out with a bit of practice. It is heavier and a bit more kinky than a hitch and rw. Hopefully we cn slim it down without cprising safety. It does the same job as an rw. The biggest advantage is the frictionless ascent

    What FEA have you done on this?
    What advantages/disadvantages does it have over some of the Petzl/other commercial designs?

    Looks interesting but overly complicated. Would really like to read more about it :)

    Petzl does not have any combo ascender/ descender devices. This goes directly up directly down. The closest comparison is the rock exotica unicender which has some usability issues in my opinion

    Yes but it does not kink the rope so you can ascend straight up and descend on one device
