Dude Takabisha is one of the smoothest coasters I've ever ridden! Gerstlauer has been doing a great job lately and Mack did have some vibration problems on Alpina Blitz and Helix.
Dare Devil Dive at SFOG was EXTREMELY smooth as well, I was suprised by how smooth it was actually
I've heard rumors the next Zelda might not even come out on the Wii U at all. Wii U has been a total disaster for Nintendo, it's their own fault for not evolving enough.
I've noticed the train rattles right after the loop and at the top of the top hat. Nothing crazy though, still the smoothest, and quietest ride in the park (possibly tied with Goliath).
