I will never go back to tedious taming traps again now that the net exists! It took me about 5 nets using SHOCK darts to knock out a level 140, and the nets have about 10 seconds before they can be used on the same dino again. Net it, tranq it, get back on your flier, wait, and land to repeat the process again. I did this by myself with little trouble other than getting the yuty to not run into water.
Also watch it when yiu think you're about to KO it. It can be hard to tell at first glance whether it is simply trapped in the net or fully knocked out.
It really is that simple though, they can't reach you or your flier on a big enough rock, so if you don't want to make a trap you can just shoot down from a rock or cliff once the carnos are dealt with. Be ready for a goose chase once it starts running.
I recommend being extremely careful flying around areas where a Yuti may spawn, as it’s roar attack will send your flier into a frenzy and potentially into danger. To tame, try trapping it and shooting tranq arrows or darts (I wouldn’t recommend anything else as this may either 1. Waste materials, or 2. Damage the Yuti so it either loses taming effectiveness or kills it) into its side/back, as the head does more damage instead of more torpor. These are great fighters and amazing for boss fights, especially when paired with Daeodons for healing!
