I was told that VXL replaced the M-Series (M91VX). I believe the Oregon M-series chains had the hard chromed cutters, I could be wrong.
But Oregon has phased out all their M-series chains from my understanding.
I believe the M-series have thicker chrome, but never heard before that it was harder. Most chain cutters are chromed (not the carbide etc ones), and I believe all chrome is hard?
Also, it sounds really strange if the 91VXL replaced the M91VX, as their special features (over 91VX) isn't for the same purpose.
