On a slightly different tack, if you arrive at Broad Stand and find something man made hanging down, don't start pulling yourself up on it. You don't know who fixed it, whether they knew what they were doing, whether it's been tampered with or damaged by rockfall, whether it's been abandoned because it got stuck, etc.

Getting to the top of the corner with all your weight on it just as it gives way would be far nastier than slipping off while trying to climb the corner.
