I have a 6-year old Husqvarna 136 with a 16" bar. It is the same bar that came with the saw. I figure may be it's time to get a new bar. I went to Bailey's and am all confused with the choices. Different types with prices range from $10 to $60. I cut about 3 cords a year of mostly maple, oak, and ash. I would appreciate any advice on what bar to get.
