I would take the 2166 over the stihl, the power head is to big and heavy for the cc's and horse power, the sides and the bottom are all plastic and the I ran my buddies band new one its very mello ,on good side very little vibration but dogs down deep into a big log even pine,and over priced also their dealer reps don't have the company support,jonsred-husky-echo-dolmar-stihl, they went down hill in many phazes ;good 32cc-42 cc-bad 43-53cc and getting their ass handed to them in 55-64cc ,70cc-80cc they make 1 good model,
