I tried something pretty close to that with my hitch climber pulley and hitchhiker. It went really nicely. I think tight rubber tubing would help. The steel hitchhiker carabiner that I have is a little bit small for standard tubing. Quick on and off at the bridge ring is very nice. Trying to get my carabiner, Bridge ring, and fixed side pulley, coupled with my layers of clothing to cooperate equals frustration.
Hey, Sean! Thanks for giving your opinion. I'm happy to know that at least one other person found the Hitch Climber pulley to work acceptably well with the Hitch Hiker. With regard to your use of the tight rubber tubing, are you talking about its use as a corner trap, if that is what it's called? Something to keep the Hitch Hiker carabiner from slipping around in the lower slot and jamming the system up? Thanks for any response you can give.
On a related note, yesterday I tried to do a relatively quick, low climb using just one rope, with just the Hitch Hiker, (with the Hitch Climber, or triple attachment pulley, for tending) a foot ascender and a knee ascender as my climbing system. As I may have said earlier, this is not something I usually do. Normally, my Hitch Hiker is used on my secondary line, and I just manually tend it.
Thanks to everyone for asking me questions about my Hitch Hiker setup, because it caused me to climb yesterday just to try to shoot a little bit of video, in order to try to show how my system works. Well, because I only had the one system to climb with, you forced me to try some things that I don't believe I ever had before, for some reason.
Well, what I ended up with before the day was over was a system that works well and self tends really easily. I'm not the best at editing video to start with, and when I tried last night I found that the Microsoft Movie Maker software that I was trying to use only rendered the video in low definition. So I'm going to have to load other software onto my laptop, or else just upload the videos straight to YouTube with no editing, and in multiple parts, which would be a pain for people trying to watch them. So I have a task before me that may take me a little while.
In the meantime, just to describe my system in words, it's like this. Foot ascender on my left foot. Knee ascender with footloop on bottom going to my right foot, with bungee cord going to thumb, as Sean suggests. I have a strong, stitched, webbing harness for tending, that is basically a circle of webbing that just barely fits around my rib cage, with a shoulder strap of stitched webbing on my left side only. (I found that using slings in a figure 8 would press against my neck, and basically choke me. The webbing strap around the ribs does not do that, and the shoulder strap prevents the chest strap from being pulled out of position.) The Hitch Hiker with its triple attachment pulley for tending is on rope. Steel biner to bottom hole. Aluminum triple action biner to middle hole of pulley, and to bridge ring. I have another piece of 1" webbing strap that is just tied onto my chest strap, behind my back, and up and over my right shoulder. It terminates up front with a stainless steel spring-loaded clevis, which attaches to the biner that sits in the top hole of the triple attachment pulley.
Once I get a little bit of rope weight below my left foot ascender, it's just walking up the rope, and the over the shoulder webbing sling works beautifully to tend the system. The width of the webbing strap over the shoulder, along with its lack of elasticity, makes it into a comfortable "cradle" if I need to take a break on the way up, and sit back. It holds me, sitting comfortably at about a 45° angle.
Thanks for putting up with my long-winded post. I'll try to post some usable video of my setup when I'm able.
