The newer saws if you limb after you fall them ,the rev limiters in the coils are pretty frustrating ,i fixed the 461 with a 460 coil ,the 661 still has the rev limiter ,if someone can figure out how to get past that it would be good i would think ,i will keep my 660 because of that .I tried the huskies ,sold both my 372's and a guy need a saw for work ,so i gave him my 395 i liked the power ,but the chassis i did not care for a few of the things .More of a run what feels best to you type of deal i guess .
