i’ve run old Macs for years and they are a horrible saw, but didn’t have the fund to move up market. i heated for many years with them i admit.
however, i think more has to do with operaters than the saw. good gas, sharp chain, most saws will do fine.
that said i’m currently running two stihls and one huskie. i like all of them.
now something that has NOT bee discussed here is the depth gauge. a few years back a guy who has cut for 6 buildings for 20 years pointed out that i should be grinding my depth gauges down to get a faster cutting saw. i had him do it on one of my chains and OMG, i will never go back. i have about half of the gauge ground off and it makes an incredible difference.
now, after having said all that, if you’ve not cut for a few years so that your habits are ingrained,don’t do it. the saw can jump pretty bad as it bites in. IF you do not have a solid grip with a straight arm on the handle, it could be dangerous. BUT, if you’ve run a saw for a few years and have your habits down, it was amazing. Cut TWICE as fast. And even brush fast, something i’ve never found before…
Just saying…
