One tip for increased line life is to ensure it is kept moist, even wet,
never let it dry out because then it becomes brittle.

I have an old B&D strimmer and have metres of plastic line, but the tap and
lengthen method never worked well from day one and the blade vanished a long
time ago. I'm forever turning it upside down and loosening drum and feeding
the line through manually. I'm wondering if I could use a measured length of
8 strand wire.
