Nemesis. An artful craft derived from the mind of the designer who brought us the Flyer and Dive Machine and thought out how to place such an immense, smooth, perfectly paced coaster in such a tightly confined space full of engineering challenges and topographical nightmares.

Nemesis is special. If you want a huge invert, Alpengeist and Montu are hundreds of times better.

Alpengeist, Montu, Pyrenees etc.
