if you had to cut up a few cords of firewood, do some felling of 18 inch dia and less trees, and clean up, would this saw be enough? i was currently looking at the 6400, and the 361, but the more i read, and have been thinking about it i feel the 5100 may be the way to go. it is small enough for limbing if needed, and seems powerful enough for larger stuff. so if you were gonna have 1 saw to do what i described would this be enough? i don't wanna make the wrong choice and be disappointed. if not thats fine. i want honest opinions, and your experience and expertise is needed to help me make my decision. i am a carpenter, not a arborist, and appreciate any input here fellas.
