It's more for
racing. This is a cruising site. Not saying you can't ask the question here, but I am saying that I doubt you will get a lot of replies. Contacting any of the above would be your best bet. Apart from that, these synth fibre lines have a limited life. Less than SST. But the
racing guys tend to change the rigs over far earlier than the lines life expectancy. When they have mega dollars tied up in the
mast, the rig becomes a small cost of insuring the mast stays where it is supposed to.
