I will just use two deadeye rings if lowering only. Cmi block gets involved if there is more travel to do with material like lifting or riding high/speedlines.
Funny that the gear head instructional and review channel pulls out a fancy piece of machinery and blows it to pieces. Almost as if he spent all his effort trying to dispense info and talk to the camera without bothering to learn anything about something new to him.
Seems like everyone handled the safety talk well since I last dropped in.
You eager lads should def have supervision. I was the same way as a teen, up a tree with a hacksaw, dropping ailanthus with hatchets, falling off moving cars.... Vital stuff for your development, but try to skip the scars...

You called?
Tieing in a second time with rope from your tail is always available for controlling lateral movements in treetops. Coming back to plumb on an original anchor is done by 'draggin' tail. A second device can be used, a closed Blake's hitch mrs, a pulley or plain biner or...
Picture and old assembly line factory or foundry when the shift ending steam whistle blows and all the workers clear out in seconds, dropping everything.
Alternatively- look Ma no hands!
The dead ring/thimble kills the prussik choke. Threading your rope through an empty prussik will not ever beat tying a normal midline knot for me, nevermind a special preloaded prussik on a dowel!
And leaving it on the rope all the time? Sure I have a great spar anchor but hold on, first I have...
Tom's point can be expanded to the KISS principal.
The problem can be solved with rope alone. Everything in the pics is safe enough. One point though:
Basal anchors need to cinch tightly around the stump. Putting friction inside of your choke loop will reduce the friction against the tree...
