I just use a 1/2 nut on some mono-filament fish-line. Shoot it between the branches with a modern slingshot.
This tree was too close to the house and it was leaning towards the house (about 7 degrees).
There is a 3 foot drop-off just behind the tree which made it more unstable.
The two nylon ropes allowed me to drop the tree cleanly between the deck and my solar mount.
