The WP chain I am ordering is the 30RC not the XC.
The RC is what I was told was Carlton, unsure about the XC.
Of course that could have changed by now. This was in June I was told.
Are you thoroughly confused yet???
Anyway you go, I would try the chisel chain you got with the saw and see how sharp it stays for you. If you are looking for quick cutting, that is the way to go.
Touch up the chain when you refuel and take a break and it should be just fine. After you get the hang of sharpening, it should only take 4-5 minutes to "touch up" a chain.
Don't let them get dull, watch the chips coming out and watch the top of the cutters. When the tops stop being clean and start getting residue burnt on top, touch them up. A couple of passes with a file should do.
Remember in full chisel, the "corner" does the cutting, make sure it is sharp and undamaged.
