Now I know some of you grizzled veteran climbers are thinking this CW climbing system could only be used in ideal trees with an unobstructed vertical path to ground for the CW/compressor to do it's thing?
In a strictly vertical path yes, but by off setting the path to ground via a redirect by a few degrees, it becomes possible guide the counterweight out of the canopy with a supporting speedline/pulley, and guide it to the ground along a known open path. This path to ground can be configured to actually support a leaning tree as it's being trimmed by running the CW guide line 180 degrees off the tree's lean.
I'm sure there's a mathematical formula that can tell you how much increased counterweight is necessary to offset each degree from vertical you guide the counterweight to ground from.
Just think speedlining with a haulback, with quite a few more bells and whistles.
