Like most climbers in my area, I use a rope bag to avoid having to reflake the rope after every climb. The downside of this is that the rope gradually aquires twists and after enough climbs, the rope can become twisted enough that it occasionally catchs in the belay device while lead belaying. This is a problem since that can take a few seconds to fix which results in insufficient slack for a moment.
The solution is to remove the twists from the rope after every 5-10 climbs. This is easy to do by pulling the whole rope through an anchor after rappelling.
The problem is that sometimes I forget to do this and have to deal with the twists while belaying. It is more problematic with a GriGri on a thin rope but can still be an issue with an ATC on a thick rope.
Are there any good techniques for dealing with twists while belaying? A method that allowed me to stop the twists from jamming in the belay device while continuing to belay normally would be ideal.
If the rope were extremely twisted, I would stop the climber and flake it, but I have never had it get so bad that this was necessary.
