Well, if any thread could start a fight I guess it could be this one!! No fight intended............... I'm no pro, but I do use full-comp, full chisel chain. I have been using Oregon LPX over 33RS chain for a long time because of three things: 1) It's cheaper than Stihl chain 2) It's easier to sharpen than Stihl chain 3) It cuts well One can argue that the harder cutters on the Stihl chain wear better and stay sharp longer and that offsets the cost difference. But I disagree. It also wears files out faster which adds to the cost. Your thoughts?
