In my opinion if your going to be using a 24" bar you need to step it up and get the 365/372
I'm starting to lean towards 346 w20" or 365w 24".
Lean away from a 346 with a 20" bar, it works best with a 16" or 18".
Personally, I wouldn't even consider a 50cc saw if I were going out to fell trees and make money when all I have is a climbing/limbing saw. A 50CC will be worked beyond it's design when you have to buck up large trunks to earn your pay check. A 60CC running a 18" with optional 24" or a 70cc running a 20" with optional 28" would be my route of choice.
There are some smart folks on this board pushing you toward a 65/70CC saw for a reason.
