Susan, No I have never even heard of Anker blades. When I need a 0/2 blade I use Olsen 0/2R blades. They track fine for me. They don't last as long as FD blades, but they track great. I Bought a half gross of FD SR 0/2 blades, and they just don't track at all. I have tried all speed and feed rates with no success. So when it comes to 0/2, I stick with Olsen.
