You said you had some smaller saws for small branches. What size are these saws and how much experience do you you have using them. Like someone said before, a 372 is not the saw you want to deal with if there is a large learning curve involved. If you are limited in experience stick with a 50cc (IMO). If you are comfortable running a saw disregard this post. I'm not trying to be critical or judge your ability in anyway......just be safe.
