I've had some of the original Spiderwire from 1998 on my Penn 330gti.
It's bashed it's way through a hell of a hiding and I reckon is as good as the day it came out of the box.
I reckon I've lost 20 yards of the 300 yards on the original spool, I cry every time a huge fish takes me down to backing.
It's happened three times - all that money out there beyond your control.
Best thing I ever bought.
