When I bought my RedMax trimmer about ten years ago I got a pretty good sized spool of RedMax .095. At that point I didn't know there was any difference in trimmer line. As I recall, the RedMax line served me well, but didn't last long at full speed against concrete or bricks. Concrete and bricks is where the stihl Xline seems to last longer than other line I've tried. Again, to be fair though, I've only used .105 stihl line. In smaller size it might be no better than anything else.
