I seem to remember a thread on here stating the opposite,
How stihl chain cut the best out of the box and how the factory grind was somehow far more superior to a file job or regrind and no-one could duplicate the performance of the factory grind...........
So has stihl changed something? are there loops not as good?
Geez i hope not.
I haven't seen a shift in quality, could be old stock, my dealer does have a lot of that. I normally don't find a need to do any filing to a new Stihl chain.
