Flatland competition classes??

[Ante]

I am wondering what is the diference between the Expert, Master and Pro class. I mean i know that the pro is the hardest class and so but i wonder how do you know witch class to enter when competing?

look at the tricks and style of ridin the people do, if you can do the same as they do in pro, enter pro, if you can only do what they do in beginners/amateur do them and so on
