My neighbors have six bay trees (Umbellularia californica - California bay laurel) along our mutual property line. Branches coming over the line are negatively impacting my roof. I need to trim them.
Here's the problem: The woman next door has a psychological/mental condition wherein she refuses requests. Her husband knows to toe the party line. Everyone else here knows not to ask them to do anything with their yard. Years ago further neighbors were unable to get their fifth wheel out our dead end street because my immediate neighbors refused to trim their tree branches growing onto the road. It was only when their own cars starting getting scratched that they trimmed. So: Permission to trim or climb the trees will not be forthcoming.
Trees #1 through #5 lean to the east, i.e. away from me. When they eventually rot out at the base, they won't be my problem. Canopy development of these trees is primarily to the east. Tree #6 leans toward my back yard. Its canopy development is primarily to the west. (#5 and #6 reacted to each other and grew in opposite directions.) Tree #2 is on the property line, so I have some say in it.
Trees #1, #3, and #5 aren't really a challenge. The, um, um, deer and squirrels keep those under control for me. I think I could climb tree #2 from my side of the line. The challenge is deciding what to cut. Tree #4 is the big problem. The offending branches are 40 to 50 feet up. Tree #6 has offending branches from 15 feet all the way to its top. It has both access and strategy issues.
Options:
Bucket truck: It would have to park on a one lane road on a slope. The ground here is dubiously soft. The arm would then need to reach 50+ feet laterally.
Portable lift: The work is on a slope. There are also serious access issues.
Pole saw from the ground: I've cut with up to a 33 foot long pole saw. At these heights, the only option is to cut the side of a branch vertically. This usually results in a pinched blade when the branch starts drooping.
Pole saw laterally while climbing #2: #4 is too far away. #6 is even further.
Ascending straight up a rope hanging from #4's branch(es), staying on my side of the property line: I think the limb is still too small, too far from the trunk.
Tarzan swing while climbing #2: Maybe with a lateral line to an anchor 100 feet away...
Scaffolding: I have some. I could build a tower along the property line, bracing it to the house. And then use a normal length pole saw...
Gadget: Somehow raise a saw up to the branch(es) and operate it from the ground.

Any suggestions?
