D Man said...PS i snapped some lines yesterday... Probably due to leaving them wet ALL of the time so i probably raided the lines off the bar that was dismantled for you...

Spectra and Dyneema are the trade names for the line we use in kitesurfing, the chemical name is gel spun poly-ehtylene a long chain polymer.
Its is unaffected by water immersion at all. Tests were performed on this stuff in concentrated acid, it was left in the acid for 2 years, and after 2 years it had lost less than 3% of its strength.
Lines break because of knots in them, wear from having twists in them from doing spinning tricks, getting damaged by hitting other kite lines or hard objects, being overloaded, contamination between the fibres by tiny grains of sand and salt crystals, etc, etc.
One of the only downsides to this type of line is the low melting temp of around 300C, so the heat from friction is what damages it when you hit other things.
So don't sweat on leaving your lines wet.
