I know this has been brought up many times before. I'm looking for a replacement bar for my Poulan Pro 300 to replace the factory 22" bar. I have a much larger saw that I go to when it comes to big stuff and would rather have an 18" on the Poulan. I know finding a bar in 3/8 and with the appropriate mount might be a bit of a wild goose chase, where as .325 seems like there is a number of options. What is my best option here?
