If people were all being taught properly there wouldn't be a thread about this. People think they can belay on all devices if they are good with one. That has pretty much always been the case until the gri-gri. And people will continue to make that false assumption. If you know what you're doing you should hold the brake line...unfortunately most people think they know what they are doing until it's too late, and their instincts will kill the climber.krampus wrote:ultimately, I fully believe everything that THB has claimed, I just don't think its relevant for real life situations, reducing the force on the gris gris by pulling on the climber side can and does happen, shamis' method of letting go does work 99.999 percent of the time but your break hand works 100% of the time and therefore that should be the method that is taught to noobs, anything else is silly and encourages a culture of laziness and pain, your whole life can change in the blink of an eye, why risk it.
I've seen 3 gri-gri accidents. I've seen 3 pinched cams, and 3 burnt hands. It's always the same.
