When using a system such as a Hitchclimber Pulley with 2 Carabiners, there is at least one distinct issue that a climber needs to be aware of. When the friction hitch is collapsed, you don’t want anything with bulk above it being pressed against the climbing rope that would prevent the hitch from grabbing.
Without a clean setup, a friction hitch can be prevented from auto-setting. This was the main issue with the initial soft-tethered Rope Wrench setups, and why the rigid tether is preferred.
