Yes i'm finding that interesting myself but more from an aspect of an outsider that doesn't really know **** about chainsaws. All I know is I like sharp chains and a saw that won't bog down. For what it's worth I started off with a used Worx electric saw with a dull chain 2 years ago struggling trying to cut down a shade tree where leaves kept falling on my boat.
Now i'm into growing mangos and avocados and i'm prepping to free up some land to plant my new trees in the spring. Since it's all on a hillside i'm going to wait until the spring to cut them down since I don't want to leave the hillside barren during the winter rains. Again....still a novice.
