Its probably my 2nd favourite braid behind the daiwa braid i've now got, most braids experience colour fading and thats not a sign of weakness, a lot of braids are the same colour underneath and just coated in yellow, green, pink or grey on top.
Fins like Tufline can fray around knots a little bit but nothing too much to worry about, if you think its too serious just put a bead in front or over the knot.
