For those who don't know what tricking is, I suggest watching this man on youtube. He is (in my opinion) the best right now.
I don't think that the debate on what defines a tricker/trickster shouldn't be on what moves they do, it should be on their mindset. Are they thinking about tricking everyday? Are thoughts and combos running through their minds? If the answer is yes, then they are a tricker, it doesn't matter whether they do kicks or twists.
Division isn't what makes a tricking community, it's a unity of like minded people.
