I don't know about some of these guys. Personally, I like a bigger saw. I hear all these comments about how the weight savings of the smaller saws is better, but I don't agree. My small saw is a 372 and a 572, and I run a 660 and a 395 when I'm not messing around. I would rather work harder for a short amount of time than less hard for a longer period. I can do in 15 minutes what the guys with 60cc saws can do in 30 or 45. I'll gladly take a powerhead that weighs a few more pounds in exchange for the increased power. The 32 or 36 inch bars make it so I don't have to bend over much. Personal preference, but I'd go with the 390 or 395 and never look back. Better yet, look for a 592! It's been on my want list for a while. I've never regretted any money spent on quality tools. They perform better, give you more pleasure, and if you get in a bind they are always worth money. Personal preference, but I say go big.
Good luck, Cody
