There are more videos on that channel, but its mostly rope access, rescue oriented. The takeway is that you can use foot ascenders with a grigri style descender. http://taz3d.fr/?lang=en for 10-11mm rope They seem to sell for around 155 euro / 180 usd, plus shipping. I'm looking for something similar to a Petzl GriGri or Rig, that wont hockle my kernmantle line to death. Sometimes I tend the rope over the front lip of the Rig to avoid it but I know how touchy they can be if you arent tending the rope correctly. If I'm not limb walking, I just want something really simple to set up. The wrench takes a minute, and I'm not ready to buy a Rope Runner since the RR2 and the Akimbo are out next year.
