The colors don't go with the name, but since La Ronde does not have Six Flags in the name, it can not be called Superman.
This might not be me, but I would thought they would build it about as fast as Goliath(SFOG) since it can get cold up there. Maybe there is more ground work to be done, and that is taking a lot of time. I know that most coasters do not go up as fast as the other Goliath, but with the parks location, I thought the workers would try to build Goliath quickly.
