Double Spoc; top rope solo

[devnull]

Not sure how active the rope solo scene is on fedi, but I figure I'd ask.

There's been quite a bit of discussion over the years about various systems, but the modern consensus seems to be to use two progress capture devices on a single (or dual) fixed line, with one suspended higher than the other via use of a neck strap or chest harness.

By far (at least in North America) the consensus seems to be to use the Petzl Microtraxion.

The Edelrid Spoc seems to be a good alternative, is both lighter and cheaper, and is also mentioned occasionally in discussions about TRS.

Brent Barghahn is seen in this photo in a double-Spoc setup:

Any potential problems I should be considering?

In general, or specific to the devices?

Note, I only read/watched information on TRS.

Regarding devices in general, the most crucial things seem to be carabiner cross loading and devices getting unblocked.

Regarding general aspects it makes sense to analyse all steps that could fail and check for mitigations.
Like #Edelrid is doing in their Lead Rope Solo risk analysis video (https://www.youtube.com/watch?v=mTTDRX6RTWc).
But I think more details could/should be included.

For cross loading, you might have seen the latest video by Yann Camus already

And for other risks to consider, there is also the #HowNot2 episodes on Top Rope Solo and Lead Rope Solo.

@mkroehnert@social.tchncs.de I actually hadn't seen the latest video Yann put out, so that'll be on the list tonight!

@HowNOT2's video is actually how I got interested in TRS in the first place! Really good and straightforward explanation of the mechanisms and risks involved.

@pmonks@sfba.social @mkroehnert@social.tchncs.de That's a good list, although your two thoughts ended up being six

I've thought a bit about the idea of using two different devices. I was about to pull the trigger on a CAMP Lift, but I wasn't convinced of its safety given its tendency to no longer engage when grabbed or tilted (against a rock perhaps?) — additionally most rope soloists who climb with progress capture devices (again, talking North America) seem to go with the double-trax, which also doesn't satisfy the "two different devices" constraint.

I will have an ascender (a tibloc + PAS) and a descender (Mammut Smart).

As for rope protection, I was planning on re-fixing often so as to not worry (too much) about edge protection.

Lastly, will be running all of this on my garage anchor board to get all these new skills (and devices!) tested for real before I get out on rock!

I forgot, that #Petzl has a collection of articles regarding Toprope solo.
Including a non exhaustive list for risk analysis.

You can find them at the end of the following page, where the first article is called 'To read for self-belaying'

I use microtraction, an old ushba and a homemade neck/elastic loop. Works fine. Ushba is primary, micro traction is secondary. Very smooth. Pay close attention to how your system performs in overhanging terrrain.
