Hitches also weaken the strength of your rope. The first hitch would split load around the tree so it wouldn’t be any worse than the normal girth hitch around the tree, the second hitch is a single line hitch and the carabiner locks it into place. As long as the system is tight, I wouldn’t worry but as per usual, a fall with slack and I would worry about that hitch snapping if you were on that particular leg. Overall I do not truly have a concern though because he is using it as a redundant connection point. Also if you are worried about the carabiner being the point of failure, a steel delta link would also work there in place of the carabiner
On his other video he is using the fact the it can be double weighted and the tag ends can be advanced and tied in to pass your original hitch point. This leads me to believe it is his version/answer to 2 tether climbing. Although if you take a linesman rope, 2 tether climbing is still just as easy as well as safe. Interestingly enough he made a webbing and 2x4 to use to stand on instead of standing in a singular foot loop. I did that a couple years ago. As long as it is weighted and your perfectly vertical it works well to help stand up however it can be prone to kicking out and Is very noisy. I had no idea what 2 tc was or that people did it. After researching it, I made some adjustments that seem to help with stability and to some extent the noise. It’s stil safer and easier just to climb DRT or SRT though, at least in my opinion. I don’t see guys being out in the woods at dark and repeatedly tying these advanced hitches in the dark when they want to get up the tree before that buck starts heading back to the bedding area. We need people like JBR to push the envelope and bounce ideas off of other people. Sometimes it creates all new methods. Sometimes it lead to vast improvements on existing methods. And sometimes it just leads to 15 minutes of fame. Either way I still like that he is trying new things. Although I’d feel better if he would have some published drop tests showing these hitches to be safe before introducing them to the mass influx of new saddle hunters, many of which have never used ropes to climb
