Searchbar and/or trick tip cult.
Do it on a tramp, do that on snow. Grabbing safety/japan makes it easier to get it around. Throw it with a bit more power than a regular 5 for the first couple times and once it gets more natural it's the same force to throw as a 5 but at a different angle basically. Just try it, it's a moderately safe trick if you don't venture over into rodeo territory and you can see your landing for like 75% or trick.
