Four Paws said:It isn't overkill if you are running it on a CSM, or if you have a need to pull a 48" bar routinely - cutting 8' DBH trees. Otherwise it will lighten your wallet and build your muscles. There are better choices out there.
I agree that the 3120 is a bit much for dragging around the woods.The 7900 is a good saw so is the 372,575,385,390 any of them would be a good choice.We have a few 3120s that we race.At the races the 3120 has been on top for about the last ten years or more.(in the chainsaw class)
