I don't exactly recall that choker, Cory, most likely a few strands minor fraying at the splice. Hopefully careful enough about that, a good concern though. Glad you picked up on that method with the sliding choker. It is a method that the main operator that I usually work with came up with. He does mainly tree work by far, and likes to roll with only a sub hook size, and it does simplify things a lot when lowering and pulling up through the crown. Other guys will have you cutting limbs to get the main hook through with a lot of those conifers, and getting into the tree is simpler as well. I will be the first to say that it can be seen as a controversial or unapproved method. Carl gave me a kind of a lecture about it once and I understood his good opinion. It does kick out the wedge socket at a funny angle where the cable joins to the collar, and also puts a slight kink in the cable. On the good side, we have used it successfully for what must be ten years now, and on many very large heavy trees with never a problem. I won't say that having your climb line through a ring on the hook with the cable there too, lowering yourself down on your hitch isn't a better way. We will do that as well. The slider is a more common practice with that operator though. One of those things I guess, perhaps not advisable but experience allows you to trust it. I don't know anybody else that uses it.
Zack, I've had branches get in the hook as well...why just today.... and so far once under the safety that had me worried. Can't be too careful and observant. Stop means immediate stop when communicating with the operator.
Welcome, by the way.
