Hi! First time poster here...
I wonder if the reason they would not go with GCII is that it would cost too much money? If I look at Lake Compounce who spent top dollars getting GCII to come in over two off season to fix Boulder Dash, which never had issues as big as this one... On Boulder Dash, they retracked most of the ride, rebuilt whole sections, added footers and additional structure to the turns and even made the ride more exciting by adding a double up at the end. Also, maybe if they would get the Millennium Flyers, the maintenance department could not maintain them?
