As previously said earlier in the year ..... I've only used a GriGri on one occasion and as a lefty, they are a real pain to use as your forced to use them right handed, from this aspect I would have thought using them in a fixed top rope set up in a gym would be an issue.
For those using the GriGri for the main reason for dogging purposes, it's just a easy to clip an ascender attached to your harness via a loop, straight onto the rope. When the climber is ready to move again, lock the ATC and then unclip the ascender. |
