I tried it last year,
I like it. I use no sticks, single rope technique. I install my paracords loops pre season and i climb the rope with an ascender.
This setup is very light, no sticks to carry and very fast to climb/descend.
I like the fact that nobody can see or use my traditional treestand or hunting spot.
It's also more easy to shoot at differents angles as you can move around the tree compared to be sitting.
It's expensive to be equipped too. 1000$ but, no need to buy multiple stand so....
I'm sold. but, it's quite technical and you need to practice to be confortable and safe. Not appropriate for everyone..
