I"m running a Husqy 353 and a Stihl MS311, both with 20" bars and don't really see a need for anything bigger. Now if you're planning on lumberjacking for a living then maybe a bigger saw would be apropos. I've got 3-4 100ft+ black spruce on our cabin property that have been spruce beetle killed this spring and will have to cut them down and either of those 2 saws will get it done. Spruce beetle infestation is bad this year.
