I Build and Run Ported Saws !
That’s why I run STIHL chain (ps 63 and RS ) Magnus , maybe not the “Best” off the roll , but after a few sharpenings they cut well ...and for bar STIHL or Cannon ... flip bar after maintenance / sharpen chain ... I have cut and split 1000 cord easy ... I recall something about the bars not lasting long because of inferior steel
