The layout still seems off, if the rectangles are outside AA's, the current layout sure doesn't use them well. I'd assume the track goes parallel to both of them, one of the left, one on the right to be fair to both sides of riders. Plus, I sure hope the little round show building isn't taken at speed, as it will be almost unseeable during the day. So, I'd expect a straight launch out of it. Plus obviously the final show building should have a pretty big, slow section. Likely entering in one end, and coming out the other.
I don't know the source of the layout, perhaps someone infinitely more knowledgeable than me.
