It's always fun to find out how someone else would change a roller coaster. Here's the topic where you can do just that. You can take ANY roller coaster and redesign it ANYWAY you want to! You can do something as simple as say "Make Top Thrill Dragster 500ft tall and 150m.p.h" or something as complex as " Add 3 loops To Demon and at one point have it race American Eagle." The best part is, you're using your imagination, so it doesn't have to accually be possible in real life. It would be better if it was, but if you want to, for example, have Batman the Ride go through 50 loops, go for it!

I would change V2 or Wicked Twister (an impulse coaster) and keep the launch track, but make one (same length) on the other end. So you would have 2 launch tracks, one on one side, and one on the other. So now when you hear "Clear For Launch.........Goodbye," You either launch forward...or backward. Of course, you would need to adjust the LIM's speed settings to a lower speed because you'll be gaining speed along the way. If you don't you'll have too much and possible cause harm.

Have Fun!!! :D

This is unrealistic:

Change Deja Vu to The flying Deja Vu.

Literally, have the whole thing lift off the ground and fly while you are riding the roller coaster.

Now for a realistic one:

Make Demon longer. Put something else between the loops and the corkscrew. The coaster is way too short now. It needs more.
