I was idly looking over wesspur's rope catalog, and noticed this in one of the descriptions(emphasis added)...
What is the thinking behind limiting stretch? Annoyance aside, I'd think stretchier lines would be safer within reason. A rubber band bouncing you around probably wouldn't be good. Any thoughts? Even better, are there ANSI whitepapers that get into the selection process/debate over the various specs?
Arborist Climbing Ropes are required to have a minimum breaking strength of 5,400 lb (24 kN) when new, and should be no smaller than 1/2” (12.7mm) unless the employee has been trained in the use of smaller line (down to 7/16” / 11mm), and the line's working elongation should not exceed 7% at 540 lb load.
