check your spool. sometimes there is a rough spot that is causing the line to break sooner than what it is supose to. after that experiment with other brands. I like the orange husky .095 line, It lasts along time for non particular areas. for areas that really need to look good I like the titanium silver brand from husky.
I run .095" Redmax and Gator Magnum in my Redmax trimmers with good results. The Gator Magnum is square, cuts cleanly and lasts a long time. Any momofilament line will deterioate from UV rays, so don't leave the spool exposed on your trailer all the time.
I will use just about anything except Echo brand line. I mostly use the brand Home Depot sells, not sure the name but it suits me fine. I bought the Echo line once expecting better results (not that the other was bad, just figured Echo would be better) and was not happy.
