I have a FS250 that is my primary string trimmer and I also use it as a brushcutter with the chisel blade. I have wondered about purchasing a dedicated brush cutter FS350-550. I usually am in want of a sharp blade long before I want more power. What is the advantage of the bigger machines? Is it only advantageous in heavy brush? I am primarily using mine for saplings/small trees. It cuts trees up to 2" without any real problems, but if I cut only 1" and smaller, the blade stays sharp a lot longer. Thanks for any input.
