Super efficient: very low friction in the advance, virtually no sitback
Precise, reliable control: when set away from your body for limbwalking, you get positive control of your balance and motion without any “slop” in the positioning

Here's another configuration for the uSAVER.
You're kidding me, right?
Nope. Two pulleys.
And a quick fix for when you forget to pre-thread the throwline through the large ring.

And the answer is ... don't use it as a lanyard adjuster...
Hi Tom,
So I double checked the tech notice on page 5. That was actually the zillon product being used for work positioning. You can view that product here...
Thanks, guys. I agree.
I've gone back with this question ...
Conrad,
Thank you for your quick and courteous reply. Terrific customer support!
Since my question involves life support and your answers will be in the public domain, I want to be absolutely certain that we are communicating...
I contacted Petzl about using the ZZ as a lanyard adjuster. Got a nice, fast replay with this link:

No problem here ... that use is illustrated on Page 5.
RTFM!

Guys,
I’d like to hear if you think using the ZZ as a lanyard adjuster is a mis-configuration of the device?
In another thread, I posted to Monkeylove asking about using the ZZ in a “climbing in a loop” rig:
Then today, I shifted my ZZ to my side Ds to get past a branch and it dawned on me...
Monkey,
I have the ZZ, tried it, and this is a definite NO GO.
Petzl says don’t use it for SRT. I believe this is NOT due to the usual “hitch release” issues. Watch carefully when you release the lead end of your climbing line from the “normal” connection hole. You will see the ZZ re-orient...
Nice wrap! Thanks for the tip.
The little tab is specifically for prussic minding. The 1.5" and the 1.5" double don't have it for some reason.
In this application, I'd favor the Omni over the Pinto particularly if I had a rope bridge. I'd mount the Omni into one of those Petzl split rings...
Richard, this is great work. Thanks for the vid. I have to say that I'm in agreement with the general discussion here. Pulleys aren't necessarily the "best and final" answer to every type of climbing. In my very first vid on the U-SAVER, I remark at how surprisingly well the three-ring...
Guys,
This video shows the uSLING and the build details. The production version will be available soon from TreeStuff.com.
Two more videos coming: applications as a plain sling and pimped out with Omni and Revolver as a midline attachable friction saver for DdRT or line Aadvance for SRT...
Pensafe has discontinued manufacturing the 2.5" ring used at the head of the uSAVER. TreeStuff has come up with the answer.
Here's the short version:
slightly smaller
smoother
certified
don't use the Pinto Rig anymore
stay with the West Marine .5"x2.5" for rigging apps

Maybe the best way to improve a Unicender tether is to get rid of it completely ...
My saddle is an old Traverse with a klutzy old web bridge, so my "saddle ring" is a big HMS biner directly to the bridge. If I had a rope bridge, I'd be tempted to try one of those new Petzl rings, mounting...
Wow, this is a first ... I'm turning loose a new idea and it's ALREADY available commercially, at TreeStuff! Those guys are moving at warp speed out there.
Special thanks to Luke for the confidence, Nick for the design collaboration and Bill Piper for knocking me into motion on the basic...
Hey Frank, I do something a little like that ...
I use the Buckingham Spreader Snaps across the forward Ds. The dual snaps act as a SRT "hard bridge" with a center tie-in hole.
It's get my attachment lower, it's more efficient than a rope bridge that alternately compresses and releases the my...
Good questions, Kevin, and I don't think there's a one right answer for you. This is a system that can go together a bunch of ways. I think the core idea is to get to the usefulness of a small rigging whoopie that can be installed from the ground and still be choked on a stem.
I've got X...
Holy smoke, Kevin! You’re making me work. Great questions, I’ll do what I can but a lot of this is over my pay grade and would need some physical testing, for sure.
First, let’s think about the tenex whoopie with the small Pinto spliced into the loop and a “large” XRR in the Brummel …
