Man, the thing's a beast. It's heavy but well balanced and with the double shoulder harness, it's just fine. I put the Echo quick change cutter head on it with three strings of .155" Echo X-fire string. WOW! My old Craftsman trimmer wouldn't even swing a double string .080" The easy start on the Stihl is pretty darned neat. It's very expensive and not for everyone but I've got so much to cut, I needed a beast.
