Watching games from around the world is an excellent way to see how this game originally started and how it is run in its natural state. In wealthier nations the game is well polished. Yet its root is something very different and more casual. When people say there is a right and a wrong way I would say no such thing. There are more polished ways and more natural ways. The polished ways take additional training in order to get more out of the horse and out of yourself.
I noticed they seem more relaxed about the lines of the ball.
Other than that, I didn't see much differences.
If someone can see something more than I do please comment below!
