LMAO! thanks clydesdale given others input I pretty much deduced that what it had to be, (not the white hairs part though) given the 5th has no load and upon inspection it is a 12 strand rope between 2-2.5mm
JGTR: Thanks I agree totally 5th line carries <50lbs, (unltil you flag it) I pull on it all the time. wasn't thinking it through.
Was just worried it might be a length of unobtainium with ultra high break strength. but PBO and Vectran aren't suitable for UV exposure so it pretty much has to be dyneema, SK 90 doesn't have much better strength (in those small sizes) to be significant nor is it commercially available in <3mm sizes so I put in an order for some of the 2.5mm.
Billie: with a 1600lb break strength, a reasonably prudent engineer would think twice before tieing a knot in this line Rule of thumb is ~30% decrease in strength with a figure 8. The smaller the rope diameter the worse the effect will be relatively speaking this is SMALL rope (10mm rope for example sees a 15% decrease) All this stuff has been spec'd with a factor of safety and likely accounts for some wear and degradation and is backed up by abusive testing and warranty/field reports, so you Might be OK..Just understand you've significantly weakened what is likely the highest stressed component on the bar and it hasn't broken.....yet.
Definitely negating any benefit from the extra strong front lines north puts on.
If you can do eye splices (easy and a good skill to learn if you can't) this stuff is really cheap to buy if you want to shorten your line with more confidence.
