Belay carabineer
I use a smart alpine, which is a twin-tube version of the Mammut Smart. There is an odd motion that you can do where the curve of the belay biner can bind in the device, locking it up and preventing rope from traveling in either direction in it. I think it is better to have the wider belly, as well
