Gonna give you a reason to start a war on Australia!!!
Holy craP! must have taken you 9 hours to set up rigging and add all that necessary bling to help you with that prune job in that barren deadend road.
All you were missing was a few spider legs, a knuckle boom and a spray rig and i swear, you showed the full bailey's catalogue!
With the high point you had,and no hazards below,why dont you just cut and chuck????
Thats a two hour job,max,in Australia,that is, if you go against Australian pruning regulations(or is removing the top of a tree accepted in North America??)
Stay happy my friend!
