Thanks to all. My trimmer is a Straight Shaft.

Colbyt, how long does a pre-cut string typically last? I imagine I'd
need more than one per trimming, as I've typically needed more than
one "bump" per trimming.

Mike, it depends on what you are trimming and your skill level at not
hitting stuff. Each little string with this replacement head is cut to 8-9"
so when it breaks shorter than 4" it is time to replace it.

I will use yesterday as an example. I went to a rental house I own which
has chain link fence. The fence rows had not been trimmed in for a couple
of years and the orchard grass was about a foot high, a few weeds and young
Chinese honeysuckles mixed into the mess. While doing 2 sides of about 200
foot of fence I went through 30-40 strings because I kept hitting the damn
fence. At bad as that sounds I was only there about an hour. Chain link
fence is the worst thing in the world to weed eat around.

With the bump and go crap I would have been there all afternoon.

That was a bad day so I stopped at Lowes and bought a new roll, 155 feet
for $8 before I went to the next house. That roll will make 206 precut
strings.

I went to another house and did the whole back yard while never replacing a
single string. Around my own yard I seldom break more than one or two per
trimming session and that is usually when I am edging along the drive or
walk. On pure grass the .095 string lasts a long time
