Can anyone recommend precut weed eater line sections you've found durable? I don't want a coil, I'd rather have precut straight pieces that are in the region of 30 - 40cm long as that's what my trimmer takes. Coiled line is more difficult to straighten out.
I use a powerful mains powered weed eater, often bashing the line against concrete to cut through thick grass mats that have grown over concrete. The line sections I have sometimes only last 1-2 minutes. I got 2.7 and 3.0 diameter square line from Alex Brushcutter when I got the head 6-7 years ago, the weed eater is easily powerful enough for the 3.0 size.
Examples:
Gen AI suggested these as twisted lines are apparently stronger than straight. I guess I'd try the Little Juey as it's the thickest.
