Would this work??

I was just wondering if you could achieve the same result with a figure8 descender instead of a rope wrench in this setup I was thinking put a bight through the big ring on the descender then clip a krab through the loop

I first met Kevin 2 years ago in Baltimore where he was in the early stages of his design. At this point he was using a dmm revolver...i forget exactly how he had it set up....but in answer to your question i would say the answer is yes, it probably just wouldnt be as slick or easy to tend

thats the one

Ok that just looks like a real handful. I can see the Tree Wrench is easier than F8 system but I still don't understand the advantage of it.

Does it keep your weight off the hitch knot? Is that it?

If that's all it is I don't see any advantage over the other SRT systems. If anything it must be harder work to ascend with.

 

However, maybe I'm dumber than I thought.

[Steve Bullman]

you can descend on a single line with a friction hitch....hence the need for the extra friction provided by the tree wrench. In Ddrt, your set up transfers the weight on the hitch cord over the worked end and the tail end(if that makes sense).

 

Its arguable harder to ascend with sure, as again you dont have that leverage on your side that Ddrt gives you. but thats overcome with the use of pantins etc and you gain a huge speed advantage as you will ascend the rope twice as quickly as Ddrt.

 

Of course, if you just try and body thrust on it like you would Ddrt you're going to struggle, unless you're built like Arnie.

 

Hope that makes sense?

[Steve Bullman]

doesnt it just ascend anyway without doing the lanyard trick?

[Paul Smith]

You would have to manually adjust.

i guess i'll find out for myself when mine comes....but surely just standing up after taking a lock it would all just shift on its own?
