Durable and has held up fantastic under professional tree work circumstances with daily use for rigging and would say it has held up better then I had expected by far and it still continues to work under daily usage as part of my speed line set up which free’s up the block and port a wrap for the heavier block work as I work back down the tree and use it from the tree I am speedlining to using either a mini block or Omni block 2.6 at both base of tree and just under the speedline attaching it to either medium or large Petzl paw or a DMM rigging hub or both depending on branch length and how the limb is balancing itself out so there I no fighting the speedline and even an inexperienced groundie can run this system like a tenured employee. I did purchase a Teufelberger rope to replace the existing rope this came with just in case I ran into a problem on site not wanting to get into Bind, not sure if it would hold up under professional wear and tare and it has more then held up better then some other brands I have I have used in the past and I would compare it with Teufelberger or New England ropes as far as usability and longevity goes as I see no problems with daily usage on my post work inspection or the following day rope inspection as it comes out of the rope bag and am at 8 months currently. And some of this rope has held up better then other name brand ropes for being a generic no name when I purchased it. Making it a no brained to purchase it again when my current one is worn out and will be purchasing more to stock on my other trucks
