As far as 50cc saws go, I’ve never run a newer pro saw. Other than the poulan pro. Lol. I love the ms460 but it is heavy. Ok when bucking but I cut up a whole tree on Monday that had lots of branches and I felt that weight. Found I was wanting to use my elcheapo craftsman 42cc because it’s lighter. I imagine a saw with similar weight and twice the power would get my attention most of the time.
Back when I used a MS210 for limbing. Then I discovered the MS192T. Makes cutting brush a dream! I'll never be without a top handle for that job. Takes about hald the time a regular saw does. Yes, I operate it one handed and I know that is "dangerous" but in all these years I have never (yet) came close to cutting myself.
