I currently have a MS290 with 20 inch bar and am now looking to also get a smaller saw for light work. Does anyone have any recommendations on the MS170, 171, 180, 181, 211? I don't know much about these new "features" such as low emission, easy start, pre separation air filtration, etc etc. I'm not afraid of these new features, just don't know if they are gimmicks or actually worthwhile. Just looking for a reliable, lightweight, 16 inch bar Stihl saw. Thanks.
