I agree that for work with in Ddrt, the amount of pressure on my legs is minimal, when I am climbing on a pulley, I am using my feet almost as a rope tender. The Pantin for that purpose seems unnecesary.
As for setting up a good SRT system to replace footlocking, I would like to try and experiment with different setups. I doubt anything can replace the ease, simplicity, and speed of footlocking but the wear on tear on the body I am realizing is considerable even though it feels easy.
