Hi Lets say you have a 100' tree and you have the pull line going through a fork up the top. You have 2 options of where to tie it ... A/ Tie to the top fork (running bowline etc) B/ Tie off on trunk at base My question is, is it the same? Before you answer please consider that we are trying to settle a debate on which is better and we want it qualified with fact. Some trees such as Norfolk Pines etc are extremely difficult to isolate the top due to the volume of branches. The rope passing down the trunk makes it easier but do you get the same amount of force onto the tree because energy is transfered via the rope down the trunk, also the top fork may create a vector... I've searched and searched for some facts but cant find any.
