Guys need some new trimmer line. I have tried all different types the last one I bought was Husky Titantium that the neighbor lent me a piece when the Still stuff I had ran out. I liked it at first but I have so much curb now it can't handle it. I prefer round as the stuff with sharp edges always seems to bite itself in the head. I don't care how much it costs. I would like to be able to do some edging down my curbs without having to fill the head every other time I use the thing. so I don't have to dag out the walk behind edger all the time.
