The picture I posted of the liros pigtail is indicative of the shape the others are in. I showed the pigtails on the line because frankly they are a pain to take off and I wanted to show I do indeed use pigtails.
The point was about the difference in fraying. Fraying comes from Broken fibers which reduces the strength of the line.
Yes, colored kite lines are Coated and the color will wear away. It is common in my experience to see uneven coloring on kite lines with lighter regions near high wear points, eg. wear lines cross, near the kite where they rub during untangling, and in the loops.
I have never seen such a uniform and complete loss of color as in the Duotone lines.
The lines that we are buying as replacement are name brand high quality lines built by skilled labor, and they are cheaper.
I think your fabric analogy is a good one, your competitors are offering longer lasting and higher performance lines. Time to catch up.
The line situation is going to get more focus in my opinion. As pointed out, a lot of people would just buy new bars and that was an economical option at one time.
the click bar because of its price, changes that paradigm. There will be people using bars for a lot longer time.
We did get excited when we saw Ralf Grosel was testing new kite lines but I conjecture that was too late in design and production cycle.
Ideally I imagine the kite designers would want the new lines in their hands so they could match it with the new kites. So maybe next year.
Thanks for the discussion and taking time to answer questions. Always appreciated.
