Have any of you all compared the new sthil edger with the straight shaft (FS85) to the curved shaft edgers that are more common. The Sthil dealer swears they carry more power, which does make sense, but my mower dealer doesn't agree. I am considering a new edger and wonder if this is the way to go? Have any of you heard of any other brands, most specificly Shindiawa, that may introduce the straight shaft? Thank you for your replies.
