With my stihl saws I've always been able to choose less than what seemingly is required. They have such great power and good chain configurations, I'm able to chew through a 20" red or white oak with just an MS 250 with a 16" bar.
I zip through 10-15" oak and hickory with a little MS 170 with a 14" bar.
My MS 290 with 20" bar hardly gets used anymore.
I also know how to properly hand file all my chains to near new sharpness. Surprising to me how many men have to carry their saws to a dealer to get them sharpened. Pathetic.
