My favorite setup for TR is a minitrax as the primary piece, positioned against the chest, with a gri gri for the secondary, positioned at the waist on a seperate rope. The minitrax runs smooth and avoids build up of slack in the system. I pull the rope through the gri gri and tie off periodically where convenient.
I use this setup to allow me to fit a few climbs in after work. Can go up and come down quite efficiently. |
