Maybe you are the spike superman, but for me I can get up and down the tree a lot faster when having to do it several times on a single tree. At my age I'll save all the wear and tear on my body I can. It's pretty simple. No ground person to guide the rigged top to its resting destination. Very tight working zone so there is a need to go down to the ground and guide the cuts into a safe area in this case was about 10 feet in dia 20 feet away from the main trunk.
I still think spiking up and then tie in would be easier then the rope climb.
