    awesome! Let me know when the kickstarter campaign begins, I'll definitely support.

    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

    When will I be able to get this? I can not wait to try it out.

    looks nifty. How 'bout some instructions on to make our own!

    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
