Oregon Vanguard chain. I certainly don't prefer it but it cuts wood. Like others have mentioned, you can die grind the raker to a more conventional shape and get along just fine.
That's correct, if you've ever done it they aren't exactly fun.
Those chains can be made to cut well with a little extra hook, I have some here, just glad I have a raker grinder so I don't have to file the rakers.
