I picked up a set of these sticks when I bought the Muddy Outdoors Hunter Treestand. I've had numerous opportunities to use them out in the woods, strapped to a variety of trees. I've had them strapped to enormous Oaks, Slick Poplar Tree, Maples and Pines. On each tree they were rock solid and safe.
My favorite things about these sticks. They're super portable and pack nicely when complimented with a Muddy Outdoors tree stand. Easy and fast to setup. No buckles or ratchets to mess around with. Just throw the rope around the tree pull between the cam locks and bam! You're ready to start climbing. In my opinion, the best sticks out there!
