Intamin Mega Coaster aka Hyper.
EGF is much, much better. Goliath is much better. Even MF (which I am no longer the biggest fan) of is better. Thunder Dolphin doesn't really offer anything. After the first drop it does not maintain speed, it does not have any good overbanks, and there is no airtime.
The surroundings are AWESOME...the trick track section is a joke, not interesting at all.
No, the only airtime is on the first drop. It is all floater, there is no ejector air on it. I have sat in the front and the back.
The Japanese people are very orderly and obidient, they do not need airgates to keep them back...just a yellow line!
Hope this helps!
