Probably good if our ropes aren't breaking. :wink: Apparently, belaying is already hard enough.

That video, Caribe, is completely irrelevant to the situation AND what the video doesn't show you is that there are many biners on the market with a perfect diameter for the SUM. However, Faders did remove the SUM from the market to fix this issue.

I have loved the SUM for it's dual safety system - not only does it provide two camming points, but it allows users to feed slack without removing the brake hand from the rope. I felt like I had a grigri and an ATC in one device. And it has worked time and time again for me as a belayer and a climber, as it has for many others. I'm not discounting the situation, but I hope to get questions answered (from the belayer himself) to understand more before I toss my device.

There's no need to remove the brake hand from the rope even when yarding out armfuls of slack. People who still do that are just stuck in an old habit.

Regardless, all devices are brake-assisting, and no manufacturers recommend brake-hand-off "belaying." The brake hand must always stay on the rope.

Bullshit... The belayer should step in front of a truck for decking the leader. He let go with his brake hand. It takes like two seconds to fall from 70 feet. In those two seconds he couldn't regain control of the belay. Its obvious that the whole climbing world needs to go into stand-down and do some re-training on how to properly conduct a belay.

1) never ever under any circumstances take your brake hand off. You can swap out but never remove a hand from the brake side.
2) when in doubt refer to rule #1
3) if by chance you violate rule #1 and #2, make an appointment with your doctor to have yourself sterilized so as to remove the contaminant from the gene pool.
4) If you don't have a doctor or cannot afford one, feel free to step in front of a truck.
If you give a man a match, he'll be warm for a minute. If you set him on fire, he'll be warm for the rest of his life!

Cognitive dissonance and internal inconsistency.

They are coming back, I believe, with the capability to use any biner.

P.S. There was no safety recall for this - just a warning to make sure you had a suitable biner. I've had my grigri get stuck on a fat biner as well.

Still, this was not the issue with the failure to cam (according to the post Hugh made on FB).

I do recall posting something on here from Petzl about the momentary release of the brake hand (it even had pictures) to assist in giving slack (gently holding the cam). I do recognize that they advocate a new method, but it didn't work for me (mostly I was too impatient to learn that new procedure).

Pretty sure the video caribe posted is the only known failure case for the SUM. And my guess is that even with the brake hand on you would fail in that mode because there is almost zero friction.
