When you replace the blades the G6 are they way to go, there commercial and will hold an edge longer without sharpening. You presume right, everything Stihl. I use a brand new Echo 500 and 775 both at a new job I just took on, they supplied Brand new mowers and all new hand held stuff and they don't do impress me in the least. If I were going to buy a blower now I'd go with the New Stihl BR 450 electric start.
