I love to run an old saw now and then even if it’s just for the sound.I've got about 18 runners from 50 cc to 99 cc (a 660 big bore), and I use all of them now and then, but the two I tend to "go to" most are my two newest ones … My MMWS 261 Ver II and my 462.
They both have great power, are very light for their size, have smooth AV, air filters that need very infrequent cleaning and computerized tuning.
While I still like my older saws, there is just not much not to like with these new ones! My other saws are mostly for running longer bars, milling, or backup!
My hands and left arm for a week after I ran that SXL all day. I cannot imagine running one of those for weeks on end.
