I have a 029 that I bought new in 1994 with a 20" bar that I'm still using. Been thinking about getting a new one and that should last me the rest of my wood cutting days. I've always wanted something with a little more power than the 029. I looked at the MS291, 311 and 391 today. The dealer said the 291 will probably have a little more than the old 029. I was leaning more towards the 311, more power and bigger chain, 3/8" instead of .325. He also had a 391 for $90 more than the 311 but not sure if I need that . I have mostly been cutting dead ash the last few years and there is lots more still standing in the woods behind me. Any recommendations on which way to go?
