That 200' coaster would be really cool, and round off the coaster collection very nicely! But looking at the drawing, it seems like the last turn would get in the way of Gold Striker's Prudential Turn (I could be mistaken though).
However, I disagree with the statement above. One thing that I like about CGA is the numerous flat rides. Even though they're not coasters, they're great quality fun and honestly a nice quiet break from the wonderful thrills a coaster brings (something Magic Mountain doesn't have). Plus Barney Oldfield, while it may not be the best car ride, it's still a classic and tranquil, fun family ride.
