1. You should try practicing with classic first, and to be able to click on joints quickly.
This is Gamer Instinct, so if you don't practice, you won't be able to do what you want.
2. Then, try a variety of mods that are unique, to get you more interested in the game, and practicing your adaptability in a situation.
3. You then try a mod that is official, like Judo, Akido, Akidobigdojo, Wushu, Sambo, and some others.
4. You can then practice on one particular mod or a bunch, but you can try to master all of the official mods, but will take a very long time.
Note: The official mods have -30.00 gravity, and -9.81 gravity.
If you try a mod that has -9.81, it would be hard to adapt to a -30.00 gravity mod, and vice versa.
In my opinion, start with -30.00, because it gives you more control, and you don't fly around.
Good luck on the road to fame!
