I just tried a brand new 28” loop of square ground Stihl RS on my ported ms390. I filed the rakers to about .027. The right side needed a lot more filing than the left. It looks/feels pretty sharp, but I can’t tell any difference between it and my own round ground chain as far as cutting speed. It took a bit of power to pull it compared to my round chain. The saw sounded like it was loaded pretty good, but it didn’t seem to cut any faster than it used to.
