I know its problably a gimick but I tried this Titanium trimmer line made by Husquavarna. It does seem to last alittle longer and also cuts better.... I think its the design of the line using .095 dia feels like your using .080 dia Its a round line that sorta dimpled it cuts smoother also and it really isnt that much more expensive. Im sure the Titanium has nothing to do with anything but sales part I think they just spray alittle of it on there just to say it has Titanium in it. The way its cuts is enough for me to buy a spool of the stuff any experiance with it anyone??
