I am now finally ready to add a hedge trimmer to my equipment, and wondered what type I should get. Should I get a double-bladed version, or a single-bladed version? Or would an articulating extended reach model be good? Can an extended reach model do everything or not? Just some questions. As far as brands, I have Stihl, Shindaiwa, and Echo dealers here, and would like to choose between these three brands if possible, so if something breaks I can get the part I need at the dealer. So, what would be your recommendation? Once I get a few replies, then I will ask about specific models from the different brands. Thanks for your help.
