Interested to see how the system works with SJ and RW. I've heard it works better with LJ and RW but keen to hear how you get on Ian.

 

I don't own a LJ so can't comment too much on that. But I was under the impression that a greater deal of control was provided by the SJ with it's breaking block than the earlier Lj which was a bit more tug the toggle and go!

I've been using the RW daily since it was released (also owned a unicender for about 4 yrs) and have so far found ,for me, the best set up working SRT set-up is the SJ with the RW. There are definitely improvements still to be made for working SRT (the new ART mods that joe harris has spoken off will go some way to help this SJ set up and there are definitely some issues with the unicender that if resolved would also make it a better package).

I've tried both tachyon and 11mm static (Yale Kernmaster) with the SJ/RW and find the static (though can be difficult to grip without 'sticky' gloves) the best - it runs much sweeter through the SJ and I prefer as little bounce as possible. I chose Kernmaster because of it's (apparent) energy absorbing capabilities.

Initially I just attached the RW with a cutaway strop to the SJ set up ala Joe Harris ( a cutaway through the velcro and the krab attached to that). This has worked great and it was easy just to detach the RW to revert back to ddrt.

As I find myself rarely reverting back to ddrt these days and to encourage the SJ to self tend I've just changed that setup to a simple tether (around the krab attaching to my swivel on my bridge and through the velcro then tethered to the RW) with a DMM thimble. The tether is shorter than the previous setup so the RW engages that bit more quickly than previously and the overall package is a little neater. You can still fairly easily remove the RW from the tether and attach your rope end to the thimble for ddrt if you wish. I've the Petzl voltige chest harness ( on it's way)- the idea being it's a little easer than the whole lanyard over the shoulder rigmaroll and attached to the RW thimble (and on 11mm line) this provides an optimal situation for the SJ to self tend.

Sorry I'm a bit of luddite when it comes to computers! Hence my long painful descriptions but I will try in the next few days to put on photos of both setups. I was just reading the Treetools blog which seemed to indicate the SJRW setup didn't really work!! Don't understand the problems they're having??

Caorann as far as i understand you add your SJ into the rope and then use the tether from the RW in the same way Joe Harris connected it in DRT?

 

P.S thanks for the treetools blog i enjoyed reading it.

Set-up 1- Exactly the same set-up as Joe Harris but instead of attaching the spliced rope end to the Krab (he has attached to a cutaway which runs through the velcro and is girthed onto the SJ krab (connecting to bridge))for ddrt you just attach the RW with it's cutaway.

 

Set-up 2 - RW tether with thimble (optional) girthed to SJ krab and running through the velcro, so Ian if I understand you right- Yes to the above! Tether length should be such that the RW can be vertical just above SJ, so when RW horizontal the distance between the SJ and RW is roughly the length of the wrench-if that makes any:001_smile: sense!

Hi Ken,

 

Yes thats exactly what i thought, might go have a play tomorrow with the SJ setup (depending on hangover). I would just run the cut away straight into my tethered RW (cut away) i think the distance is going to be less than another RW but i guess i'll see what happens.

from memory too short a tether length can make advancing more difficult and can possibly lead to descending issues, RW not getting chance to engage properly as you descend so can just plummet! Think something like this may have happened to Carey Gibson...maybe he posted on treebuzz, could be wrong..just make sure wrench engages before descending(as I'm sure you know).
