I just picked up an Oregon SpeedCut bar and chain combo for my Jred 49SP. That “narrow kerf” system cut well, but I’m disappointed with how quickly and how much the 95TXL chain stretched. I’m not sure if Stihl makes narrow kerf chain. If not, would a Stihl chain be compatible with that Oregon SpeedCut bar. Of course the Stihl chain’s pitch, gauge and DL count would be matched to that SpeedCut bar. So, is there anything special about a bar from a narrow kerf cutting system that is problematic to using a non narrow kerf chain with it?
