Anyone using an Echo CS2511T? If so what chain are you using and has it been working well? I've gone through three loops of Oregon 91VXL045 (including the one that came with the saw) without any of them lasting to the first sharpening. They start to chatter worse than my teeth on a -20 degree winter day within the first few cuts. Then start to snag and stop the chain completely until removing the saw from the cut, revving the piss out of it, then gently placing it back in the cut. In all my years of chainsaw use, I've only had this happen one other time on an MS192, but It was obvious which link snagged because it was was clearly bent up and out, so I ground it off on the bench grinder and continued to use the chain for many many sharpenings. These chains on the CS2511T look fine, they just chatter and snag to the point where I'm ready to trash bin this saw.
