what is the purpose of Prusik 2? Unless its a bungee cant see the mechanical advantage in it
It parks the load while you reset prusik 1. I guess you would use this if you are trying to haul something a significant distance. You pull the line "pull here" until you can't go anymore (presumably because of some dimensional/distance limitation). While you hold the load at "pull here", you slide prusik 2 forward and it will hold the load while you reset prusik 1 for another pull. It lets you ratchet the load up in steps....or prusik 2 is some kind of safety to keep it the load from going too far backwards.
tshan...what are you working on over there?
