I've got an el cheapo Flymo one, and I replaced the plastic string with
heavy duty plastic string (available anywhere) and it's a beast.

A friend of mine said he went to a more industrial type place and they
had some carbon fibre or wire reinforced type super-duper wire and I
don't think he ever had to change it again.


Possibly Kevlar? That stuff would make great strimmer cord. Carbon fibre is
too brittle. Kevlar isn't as strong as carbon but it's much tougher. You
need special ceramic bladed sissors to cut Kevlar cloth and even then it can
be tricky. It makes the sissors twist and it slides between the blades as if
they are blunt. With a kevlar cord you would have problems with the little
blade on the strimmer used to cut the cord to length!
