We did a "Vista Prunning" last week behind 9 homes that backed up to lake Michigan. The clients wanted a better view of the lake. The slope was soo steep you could not walk on it you needed to be on rope.We were required to just prune the trees and keep as much growth on the slope as possiable to keep the slope stable. The gaps were around 50' across. We set up a "high line" between trees on the edges. We used a large DMM rigging hub to keep things organised and simple. It was very nice not to have to use any links.
