Joe, if you're about on saturday head up this way and you can try out your sj with my wrench.

I can't see there being an issue with the wrench hitting the lever as long as you keep it set properly and tend properly. The wrench weighs next to nothing so it would need an extra weight on it to pull the lever, and thats if it would even sit far enough down to touch it.

You could get all fussy and say that a forked branch might sit on a prussik and give you a drop too, but what are the chances?

In response to your message Dan are you still climbing this sat? If so wherabouts around Norwich? I did'nt reply initially because I was'nt sure if i'd be free but its looking like i will be

Saw man thanks for your reply I'm glad someone has managed to get it set up with the rw. Dan where exactly are you climbing sat?

Bump. sawman Do you have a picture of your set up please.

For longer ascents-Croll with footloop as upper ascender.Pantin. RW clipped onto petzl voltage chest harness via DMM thimble. Old photo, now have SJ mods, considering stiffer tether.

i have old bridge from a dragonfly harness its looks the right kinda length and is stiff would this work as a tether?

I'm confused too, just checked it and it takes me straight to page 80 of the ropewrench feedback thread, go to post 798 on page 80 of said thread and sawmans photo is posted there, very similar to the setup of caorran posted last night.

Yeh I'm thinking the same but like the simplicity of the ddrt/srt changeover etc.

As mentioned above, page 80, post 798

Here you go buddy, sawmans photo, save you going to the ropewrench thread

DMc is currently running his Unicender under an RW and reports that the RW makes the Uni much smoother in descent and he estimates that wear on the friction plates could be reduced by half.
It all seems logical to me and due to vastly reduced wear rates, makes the Uni a lot more affordable.

In the short time a ran my LJ under the RW, it was obvious that the wear on the LJ brake would be reduced. Descending was much smoother too.

Yep that's the one thanks Ian. The thing i really like about the set up i have is the speed that you can swap back to Ddrt, just undue the lower shackle ( from an old Treeflex bridge)and remove the RW pin and your done. I will very often swap back to Ddrt when crown reducing trees, i find i miss the fine control that Ddrt allows.
