The course is like this:
double rainbow box or rainbow rail
U-box or wave box
down rail or long flat box
9 or 15 m kicker
9 or 15 m kicker
the double rainbow is ridiculous. It's set up like a bridge over a gap, about 1 meter apart, and with metal bars holding them together. So if you fuck up the transfor, you rag yourself on the metal bars and then you fall into a pit of death. It is rumoured they will put snakes in it.
