I cut my own firewood, probably 3 or 4 cords a year. I have a poulan 2075 with 16" bar, and a husky 350 with 18" bar. My question is I need a new bar and chain for the 2075, Should I go back with the 16" or go with 14", or should I sell it and get a better small saw? Also, what is the best bar/chain size for the 350? Thanks for your help.
