The Gri-Gri will act as something of a “second-hand,” even if the worst should happen and the brake strand is released. Regardless of the context – sport, trad, multi-pitch, single pitch, trad, alpine – it is inherently safer than the ATC.

: a talisman, amulet, voodoo charm, spell, or incantation believed capable of warding off evil and bringing good luck to oneself or of bringing misfortune to another.

With a GRIGRI, it is not possible to rappel on the two strands coming out of the anchor. So one must rappel on a single strand, blocked at the rappel ring by a knot attached to a locking carabiner. Rappel only on the strand opposite the knot block; the other strand is used only for retrieving the rope.
