I'm perpetually amazed at how strong ropes are, am also frequently thinking about how much overkill we use (not that that's bad!) and it got me thinking/curious about when ropes do fail- if you've ever witnessed a failure I'd love to hear about it, w/ as many details as possible! Thanks
PS- Is there a rule-of-thumb for WLL on a rigging-anchor? I'd guess there's varied WLL's depending whether it's to hold a speedline, or to hold a line you're blocking-down / negative rigging on, but I've never heard any rule-of-thumb guideline for this and always just see people blindly over-shoot..
[edit- I actually had a chance recently to try popping a rope, a 3/8" tag-line I've used heavily the past year for pulling/bracing/etc, was dropping what I calculated to be nearly 1k onto it and it wasn't breaking, was well past its kN MBS but I'm unsure how to calculate rope-in-system for that type of thing, was still really amazing to see a puny rope take dropped loads!!]
