I have only had experienced srt on the wrench and the runner there is still something to be said about the feel you get with the wrench and your favorite cordage that can't be replaced with a mechanical but the runner is like a race car and it is my favorite so far.
Thanks for this quick response, Nasshotgun. Which version of the Rope Wrench do you own? I own the original Rope Wrench ZK-1, and an issue I often have with it is that my hitch tends to start binding up too hard on long descents, as though it needs extra help to take weight off of my hitch.
I'm pretty sure my stiff tether is stiff enough, and that it engages as it should when I sit back into it. It is probably just operator factor.
Thanks for your post, because now you've gotten me to think about why my hitch binds up fairly often. I may take to the practice of manually "cocking" my Rope Wrench to its "fully loaded" profile prior to putting any of my weight at all onto my hitch. It occurs to me that the short period of time where the Rope Wrench is normally engaging through its connection with the stiff tether, is also allowing the friction hitch to bite down onto the rope at the same time. If the biting of the hitch onto the rope only slightly outruns the "setting" of the Rope Wrench, the hitch will start out at the top of a descent tighter than it should be. While it feels ok at the start, it naturally gets tighter the further one descends.
I have had days on the Rope Wrench where the hitch operated beautifully and easily, but those days are probably far outnumbered by the days when I felt my hitch was too tight for comfort.
I'm going to try this experiment of manually setting the Rope Wrench to its most aggressive profile prior to loading up the hitch the next time that I climb. If this practice fixes the biggest issue I've had with the use of my Rope Wrench all of this time, I'm going to have a hard laugh at myself.
Just to foot-stomp an earlier post made by Kevin Bingham in an entirely different thread, he recommends using the Rope Runner's "bird" only to get the Rope Runner to start biting down on the rope. Once it is engaged, I think he wants you to use the back side of the Rope Runner to control your descent. I think that Kevin thinks that this provides better, more subtle control of the Rope Runner. Using just the "bird" to try to control descent makes for a jerkier ride than it needs to be, if I'm understanding him correctly.
I'll try to find Kevin's original post and link to it in this thread in a subsequent post of my own.
Thanks again for your post, and for making me think about things.
