So, what do you guys think is the best backpack blower out there? I'm planning on purchasing another backpack blower and I want the best, most powerful, loudest (is not a factor)... I currently have the Shindaiwa Eb630 and it's pretty powerful, I haven't tried anything else except Stihl's new backpack 4mix blower which pretty much sucked.. the EB630 blew that one away.. I plan on blowing away leaves, grass clippings, dirt, etc.. You know the general duties of a backpack blower! I dont know what else you can do with it.. So what do you guys think? Redmax, Shindaiwa, Stihl, Echo? Or any other brands out there>?
