My "big" saw is a 60 cc saw with a 20" bar which meets my day in day out needs very well. I also use a 50 cc saw with 16" bar - quick, light, and nimble. Once in a while I wish I had a bigger saw. Like when I cut pine, which isn't that often. A 572XP would be nice but I just can't justify it. I make due.
A couple weeks ago I saw on CL a used 24" bar and skip chain that would fit my 359 and bought it. It was cheap enough for an experiment. I am getting into some bigger fir so I put it on today to give it a try. A normal chain has a tooth every other drive link. A skip chain has a tooth every 3rd drive link. The idea is that with the teeth spaced further apart it allows a smaller saw to stay in the power curve when a long bar is is buried in wood.
The first tree didn't have much hinge and went a little left and hung up.
So I winched it off the stump - doesn't look promising. Bigger isn't necessarily better when it come to our fir.
By the time I got to good wood there wasn't much left. Glad I don't get many this bad.
The best one.
I was worried the saw would be nose heavy but it was actually well balanced and comfortable to handle. It cut fine but that stuff did not make much of a cutting test.
