Suppose I have three chains: (1) Sharpening angle = 35 degrees; (2) Sharpening angle = 30 degrees; (3) Sharpening angle = 25 degrees. I intend to use the saw for general purpose work which will include some felling, bucking, and limbing. Assume all three chains gave the same amount of wear and clearance above the raker. Occasionally, I may have to rip some curlies. How is the performance of each chain going to be different? Which one do you use and recommend?
