Thanks to all for checking out the videos. Another version of this system has a Pinto on the big ring side and a prusik loop as the adjuster. The retrieval is girthed onto the prusik loop to pull it over the pulley. What this allows is greater extension of the pulley through the choke, and is great for allowing it to follow you around a spar, preventing rope drag.
Wouter ~ I hear your idea about the chalk bag. My thinking was based on how I have been doing most of my work. I start with a secured footlock or base-tied SRT to my desired TIP. From there, a simple biner on the big ring side means I don't have to return to the TIP to drop a line, and droping a line might get tricky with a large number of branches below the TIP. With remote retrieval, the throwline follows the same path as the climbing line. I usually found that a choked spar would afford me more mobility, so I looked into a variety of friction savers. The A.R.T. ropeguide was just too costly for me, so we came up with this.
Kevin ~ Practice does help, or just preoccupy your entire life with thoughts of climbing, and it will come to you...I'm sure you understand! The stopper knot is just an overhand with a bight. When you pull down on the tail, the bight comes out and releases the bag.
Banjo / Treedoclang ~ The saver in the video is the first generation, before we had sourced a slightly larger ring to work with a Pinto. Jim and I talked about some options, and how little clearance we had to work with, so he suggested making the saver with Hi-Vee, which is a COVER dependent line. The core comes out entirely, meaning that the tight eyes are almost flat as they wrap around the ring. This afforded much more room than any other line. The video points out how the Cocoon can be oriented different ways, and the 90 degree set-up keeps everything nicely aligned...
AND, with the soft retrieval, it means you have control over both ends of the saver from the ground, meaning you can pull back and forth if needed to release.
Thanks again for everyone taking the time to check it out!
Happy climbing!
