This is why we made Mithril weblock (prototype for now). To rig a highline at places like Aiguilles du Diable (4100m altitude), you need to lower weight of your gear to minimum.
Dyneema instead of nylon, aluminium instead of steel. And a minimalist soft-release rigging system, no pulleys, no linegrip, just a weblock and piece of light webbing.
Danny Mensik shows the basic use of this system that is powerful enough to rig a 55 m line. And you can easily multiply it if you need more tension.
