Thanks guys. The guy I bought them from said they are harder to hand file than a stihl chain because they are harder steel. I suspected this was a sales pitch, but I wanted to try out my newest chainsaw, so I bought 2 chains, if nothing else, to try out Carlton chains. Didnt get to use it much, but seemed to cut well. If the ice and snow ever stops here Im gonna take a vacation day and spend some quality time with my new saw.
By the way, this dealer sells mainly Echo saws, and from what research I have done, Echo uses from factory Carlton chains. From what I have read on AS Echos are a good saw. Kinda tempted me a little, but I just bought a saw. OK, Ill quit rambling.
