Dillbag, that was not stated earlier, but hypothesized. I hypothesize differently, in fact, that an unattached leg loop might catch either by friction or on a bent knee.
I use a backup not out of fear for my belay loop, but mainly to back my brake hand up, should something (rockfall, whatever) happen to me. I also use it to stop on rappel, to un-knot the rope or to clean gear. And because I use it often, I make myself use it *all* the time, so that I won't mistakenly think it's there some day when I didn't bother to use it.

People have fallen out of their harnesses when they failed to properly fasten the waist belt. So there's evidence that people just fall out and the leg loops don't stop them. Maybe some of them were slowed down by the leg loops, but in the end they all slipped completely out.
If the waist belt unties, or the belay loop breaks, you're taking a FALL onto the prusik. Depending on where you're holding it, it might be a FF1 fall or greater; that's a lot to hold with just a bent knee. Especially if you're rotating backwards, the bent knee quickly becomes less positive. Also, when you start to fall, you've got to relax and let go of the prusik. But at the same time tense up the legs. That's really counter-intuitive.
Maybe it's possible, but I think it's highly unlikely.

Good point. You'd have to train hard to get that to ever happen in an emergency....

How many years have belay loops been in use? How many have failed? I'm not changing anything about anything. You can hardly think of something that's less worth worrying about than this. It's very sad for his family but please, people, lay down friction strips in your bathtub or change the batteries in your smoke detector or eat more oatmeal. Forget about this.

The most sensible comment posted on the four forums I read.

I agree with MOST of what Dalguard said except Its not that I am not going to change ANYTHING. As usual, occasionally check your gear and if its getting excessively warn, heed that little voice that says replace it, be it cam slings, ropes, harness what have you.

I have always cut the belay loop of my harness... instead I put two lockers to rap off threaded where the belay loop would go.
I was told this was a weaker system than a belay loop. I never quite understood why... (if someone does, please explain).
I always use a prossik attached to my leg loop as well.
Everyone has their own system...
