My thoughts:
- If you could avoid using slings and biners around the tree, it would make it simpler and with less points to fail, but if you needed the length of the slings then what you did was fine.
- If you could avoid girth hitching the slings, then this would be better, but again, if you needed the length then I'm sure the strength reduction wouldn't be an issue on a TR setup. The closer sling looks like it has been doubled and then girth hitched, if so, don't bother with the girth hitch, and you'll get some more length, and keep the sling stronger.
- As others have said, two, independant fig-8 on a bights, each with both biners clipped through them would be preferable for the master point.
- For the masterpoint biners (ie where the dynamic runs), I would have them spun around 180 degs. Currently they are opposite and opposed, which is great, but if you had it so the "fat" end of the biner was down, then if the movement of the biners tried to wiggle the screw gates, they would wiggle towards being more locked and closed, rather than wiggle towards unscrewing themselves, and leaving the gates potentially able to open. A small thing, but it is best practice.
- Most importantly, as others have said, the anchor is only as good as the gear (or in this case, the trees), so closely inspect them with a critical eye, keep the slings/rope down as low as you can to the ground to reduce leverage, and use padding to protect the tree for future generations. |
