You are correct in my view on your thinking regarding about raker height , and angle . It is a trade off when it comes to sharpening i feel , 1) more aggressive = faster cut but possible shorter life span between sharpening or 2) Factory angle and height = slower cut but longer life span between sharpening .
In my other thread here on Full skip , ( I use to run those over 30 years ago after high school working in the woods ) , I recently bought another chain for my 441 , all the dealer had though in my gauge was the full skip , so I said WTH , Why Not . Yes , there is a higher kickback risk , but even cutting in Madrone , a hardwood like oak here in the northwest , It rocks :thumbsup: . If I can figure out how to shoot a video with my wife's camera , I still have a log pile of tree's next to driveway , with several over 18" - 20" in diameter , that it cuts through like there is no tomorrow .
My point there though is , that running full skip = half the number of teeth , Faster cut BUT 1 , just 1 slip up by nicking a rock or other hard surface and chain goes from cutting extremely fast to not cutting worth a SH** in a heart beat .

I have been thinking about taking the rakers down but I have not done anything to them yet. I read on another forum that the guys that race chainsaws run theirs at .027'' so they will have a faster chain speed. I was thinking about trying to learn how to square file but I read some conflicting information on it. I don't think anybody here stocks full skip chain.
