Nice pictures. I have seen trimming like that but the usual thing here is they simply crop them below the level of the power line so no matter how hard the wind blows it won't hit.
They strongly recommend the tree be removed.
I have a royal palm that is getting too big and I am afraid to screw with it since the roots are also into the underground wiring. I will probably have to kill it and let it rot away.
