- Familiarity: I've used it several times
I'm sure most everything has been said about the Gri Gri already, but I had to add my experience as well. I lead rock trips for UVM Outing Club and this is makes quite a few things easier, whether it be setting up an anchor on an instructor's line or belaying a slow but determined clImber up the wall.
I didn't used to be a fan of the device, but it's value has definitely become apparent to me. I am still learning to be comfortable using it for lead belaying at this time, but other people I climb with definitely like it for that.
