I've got more than a bunch of branches in tall trees I'd like to "prune" and I'm looking at using a rope saw. I have no problem except the time spent to get the line over the branch and I'm pretty good so far w a nut and slingshot. I've never used rope saws but I see some are now made w teeth on both sides of the chain that apparently don't hang up like the old ones. I assume w 2 people pulling at wide angles on the ropes would work better than one/me pulling straight down from the branch. I'm sure I could take down small branches alone but wonder if I could bring down larger 6-10" branches w a helper and a spread more like 45* on the ropes ? I'm also thinking about renting a lift and using it to do the the "pruning" .
