My go to for fire wood is usually whatever I’ve just been working on recently with my 044 as backup and a pioneer for fun . The 044 may be an older saw but it’s never let me down , old or new preventative maintenance will keep all well built saws running along time.
I've always loved my 044. Kinda changed my attitude a bit when the 460 showed up. I like it much more than the 660's, and downright hated the 066's. Damn things burned up cylinders like they were made out of cardboard.
