I hire climbers to put pulleys high in the trees, then use Synthetic 
Textile rope with a weight on one end, the other end tied off. I find 
that the rope does NOT last forever in my tall redwoods -- tree sway 
causes the UV-resistant outer jacket to fray around the pulleys, 
exposing the UV sensitive inner braid. I've had this happen in as few as 
five years. The trees are 200 ft redwoods, and the pulleys are around 
140-150 ft. My guess is that this isn't a problem for shorter trees. :)
