Performing a swimming disconnect on a Pirana.

I'm guessing Scott meant he untwists the single strand of rope while rapping on that single strand with an ATC. I like doing this,too, and I refer to it as "squeegee-ing" the rope, as you see the twists come out the bottom as you descend. It confuses the folks I guide, though. After expounding the benefits of the Fig8 and having them use it, they then see me come down on an ATC. I then have to expound the benefits of the ATC...

Untwisting a twisted double strand rap with an ATC would be maddening! Better to use the Fig8 as Kurt describes.
