I'm looking at either getting a backpack blower (BR420) and a string trimmer (FS90)...OR the kombisystem from Stihl with the blower. the question is whether the blower is really worth a crap. I have about 5 acres of land to tend and would get the pole saw with the KM90 and possibly the edger. So, has anyone had any experience with the blower onthe kombisystem? I have pine trees and want to blow pinestraw out of a yard. you need a fair amount of arse in a blow to do that and I have borrowed a BR420 and it works good. But i don't know if the Kombi blower will do it.
