Roachy , I agree with you. I'm a firm beliver in using several ropes.Some are for conifirs only others for decurrent trees and then rec. climbing or compitetion.But I like my lines to have that furred up feel to them rather then the slick new feel.
I have four lines that I work from. The most current is the Flyline.I also use different hitches for different application too.
Although, flyline is a core dependent line, and not out sheath dependent like most 16 strands, the wear and tear we see on it , if any, is more of a visual problem for me . Unless of course the core is poking through, then you may have some problems.However, I climbed on it through some heavy barked trees to ruff it up a bit and work out some kinks before used it in my rings.This is probably what cause some of the fraying with out a doubt..
