How far would you have to fall to generate 4,000 plus pounds of pull like that on a biner?
I doubt your webbing or your body would survive the jolt. Nevertheless, I was impressed with the results of the Petzl Vertigo. Although the gate latch broke early, it looked like had you been hanging in it, and had a gate failure like that, then it appeared that your webbing might have not slipped out. All the carabiners first failed at the latch end of the gate, and not at the pin end that the gate pivots on, so maybe there is room for improvement there. And the threads on the 4mm maillon seemed stronger than the bend in the link. I did this test once on a used piece of 5 mm Kevlar cord that had Figure-8 knots in it and it broke at 5,000 pounds. I had been caving ( I used to do that ) with the rope tied to a Jumar on a Mitchell System, and used it on several 100 foot plus ascents.
