Years ago Stanley Longstaff and I had this discussion. His response was something like this...
16 strands rated at X, there are 1, maybe 2 strands nicked. It still gives you 5400 so its most likely fine. But if you question it, which you do cause you asked, is it worth having that doubt in your mind?
There was alot more discussion but that was the meat of it.
Miss ya Stanley
