Was wondering to best way to cut large hemlock branches off. They are all about 15 to 25 ft. in length. They range for 6'' to 9'' in diameter. I under stand the under cut and top cut closer to the trunk (cut fast) The last time I did limbs like this I under cut them and as soon as I touched the top with the saw they snapped. Mostly landing flat but some did hit top first and spring out. Any suggestions
