Quick draws are also rated for 24 kNI've noticed a pattern with real rock climbers when it comes to using locking vs. non-locking biners. They tend to use locking biners that are at/on their bodies or otherwise in motion, and tend to use non-locking biners in stationary applications such as on quickdraws, anchor points, etc. Not saying that is always the case, but it's a distinct pattern. And if that general thumb rule is good enough for them to hang at 1000 ft, then it's good enough for me at 25 ft.
