What trimmers do you guys run. Right now I have 2 but they aren't commercial. One of them has a special head with a 4 way string, the other is only 2. One is a craftsmen, the other homelite. If I keep using them so often I'm sure they are going to go. So I'm going to get most of my equiptment for next year during the off season. I really have no idea about any commercial trimmers. So what's good? What are you guys running? Thanks.
