Pretty slow here as well. Just can't get my mind off of being in the trees. Probably won't be back to a computer until Monday (if I am lucky). As far as that rope climbing system goes I found Menards has 100 feet of a 3/8 rope but it says working load of only 244 pounds. I used some of this stuff to put small logs with my truck. I did have it break once but that was pulling a log I could not even lift. I would think it would work for this. Just not sure. Might have to try some test this weekend.
