Guys, I suggested the 3/4 line for false crotching simply because I am not really positive on axmans level of experience with rigging drops on a sling mounted pulley(snatchblock). If I'm going to make a suggestion to a possible beginner I'm going to lead him down the safe path. Not because this job is going to have such a shock load that line failure could be possible, but for the next time he decides to try cracking the head over on a much larger heavy top. As for insulated pole saws, they are great for line clearance tree trimming from an aerial lift. Most are rated for 20,000 and are awesome for knocking a piece you accidentally lay on the 3-phase. When removing a Tree around the wires..loop is right on, a fast cutting saw will make the difference between hanging one up and making a smooth fast cut, and this is true for both roping around the wires or beating a tree down as well.
P.S...Speed Lines are a waist of time...stop watching Arbor-Master videos
