1. I use my Homelite string trimmer for edging. I notice that it sure brings up a lot of dirt and blows it into oblivion. Should I be concerned about this "soil removal" and perhaps buy a dedicated edger, or am I being way too cautious? 2. What are the pros and cons of thicker and thinner string? I'm assuming that thicker string such as .095 inch will break less easily - but then why would someone buy thinner string such as .080 inch? Thanks all!
