If I'm doing cuts in a 8x8 timber with a 39cc saw. Whats going to cut faster? My choices of chain and sprocket setup are; 3/8 square ground, 60dl, 7 pin sprocket, total weight of 327 grams. or 325, 56dl, NK, 8pin sprocket, total weight of 226 grams. I'm thinking that the 325 setup weighing less will cut faster. .
