Well since it is the time of the Olympics gonna go with that overall theme for this...

Free - Jamaica (lots of speed)
Casual - USA (You either hit gold or fall on your face but you're in every event)
Advanced - Netherlands (Not a lot of representation but Damn it's good)
Nation - North Korea (You just have to have a different mind set to be in here)
Table Top - The UK (Old School, All Hail The Queen)
