There's a million different hitch variations people come up with all claiming to be the best but they're more alike than different. It takes several wraps of any hitch to get enough friction to support your weight with different finishes to keep the bottom wrap from biting into the rope too hard. Hitch performance is as much about the right cord/rope combination for your weight as anything.
Friction hitches in saddle hunting suffer from two basic problems. With a tether they're being used in an SRT configuration which requires a hitch to support much more weight than is ideal for smooth operation. Safe yes, but with a propensity to bind up. Second, small diameter ropes and their smaller diameter hitch cords are also less user friendly than the larger diameter ropes Arborists use. That said, there's nothing wrong with hitches on tethers or experimenting, but when watching videos of Arborist setups it's something to keep in mind when they appear to work so easily.
