Wobbly wire.....

[Robbie.g]

So SS1x19 holds up a rig....has a finite strength....finite amount of elasticity.
My understanding is that the wire stretches and recovers as the load comes on and off, and when the load hits maximum elongation the wire does not recover fully!?!. (i belive it's called plastic deformation).
After after such an event the wire could no longer be uniform,when you run your hand up and down the wire it is not straight, and smooth ; but 'wobbly'. i'm not talking about strands lifted but the whole length of wire has 'wobbled'.
Should i use the 'wobbly wire' feel,as an indicator of possible overloading of the wire (either by being under spec.ed or suffering from some event that the wire/rig was not designed ).
This all seems straight forward enough in my head, but some other opinions have put in the seeds of doubt.
What do ya think?
Thanks
