Ivel:
How is the Jerry Brown One Line working for you? I have used it it bridle repairs and unloaded 5th lines but never as tensioned flying lines. Is stretch and creep a problem?
Regards,
Jake

Jake,
As always there is a bit of stretch in the front lines as they are constantly loaded, however I have not had to do any major adjustments to the set since I made them a year ago. I can't measure against the old set as the new ones were only roughly measured against my old 20m set to begin with. I think they ended up being slightly under 20m.
I have flown with much worse lines that came stock with kites
