Smoothest and roughest coasters you've ever been on

[Xenon]

Just post the smoothest and roughest coasters you've ever been on. Here are my answers:
Smoothest: GateKeeper, Cedar Point
Roughest: Hurler, Kings Dominion

I think the smoothest I've been on (considering how much the ride tears you apart) is Maverick @ CP

And I know the roughest is Shockwave @ KD

Steel-
Smoothest: Cheetah Hunt at BGT. Even though it's a snorefest, I can't deny that it is glass smooth.
Roughest: Every SLC ever, Every Volare ever, Pinfari looping zyklons, Toboggan at Lakemont Park, and Diamondback.

Wood-
Smoothest: Beast at Kings Island and White Lightning at Fun Spot America
Roughest: Wildcat at Lake Compounce before the re-track, Hell Cat at Clementon Park, and Boss at Six Flags St. Louis

Smoothest: Fury 325, Intimidator 305, Banshee, Valravn, Griffon
Roughest: Corkscrew, Rebel Yell, Mean Streak, Invertigo, Carolina Cyclone

Smoothest: Swarm @ Thorpe Park
Roughest: The Ultimate @ Lightwater Valley

I'm even game for most rough coasters so I actually find "Zamperla" Dragons to be the smoothest ones that I've ridden on, lol!

I'm fond of soft transitions, not only quick ones!

Steel
Smoothest: X-Flight, Arrow Suspended Coasters
Roughest: Invertigo (KI)

Wood
Smoothest: Lightning Rod, Goliath (SFGAm)
Roughest: American Eagle, Timber Wolf

Roughest I've done is Goudurix but even then it's not as bad as everyone says...

Smoothest would probably be Dare Devil Dive @ SFOG. It's so smooth to the point of relaxing.
Roughest would be Rebel Yell @ Kings Dominion. I had a horrible time on that ride, it was such a weird feeling.

I didn't find Rebel Yell that rough honestly. Grizzly was much rougher.

^ I say the same thing. I went to KD with a couple non enthusiast friends a couple summers ago and we all found Rebel Yell quite fun and Grizzly pretty rough. Shockwave at KD also wasn't nearly as bad as people say it is either. I've had worse experiences on boomerang clones than Shockwave.

Don't you TaLk AbOuT GrIzZlY lIkE tHaT!!!1!!1!1 Grizzly is perfect<3

Smoothest for me is Wicked Cyclone. I think I caught it between "vibration" cycles at the beginning of this season, and it was unbelievably smooth. Really surprised me.

Roughest... don't know. Gwazi and the 2nd half of the right side of Thunder Road would be contenders, though.

That's odd. I don't really remember Grizzly being that bad.

Steel:
Smoothest would be Intimidator although it is a B&M and it's one of the few coasters I've been on opening year.
Roughest The Cyclone at Wonderland Amusement Park, it's a 60's Miler Mouse.

Wood:
Smoothest White Lightning at Fun Spot
Roughest It's honestly a tie between the Rattler and Texas Giant.

Roughest by a wide margin was the old Rattler at SFFT. I rode it in 2002 and even that was after significant reprofiling had been done. Smoothest has to be any of the i-box RMCs. They're all equally comfortable. So what I'm trying to say is... Rattler is both my roughest and smoothest coaster!

^ Roughest and smoothest... oh what a big difference!

Smoothest would probably be Wicked Cyclone. RMC makes smooth rides. Kraken and Nitro are also very smooth.

Roughest has got to be Great American Scream Machine. That Ride jerks you around so much. Also a lot of painful airtime.

Smoothest: Twisted Colossus

Roughest: Giant Dipper at Balmount Park

Smoothest - Probably Swarm opening year

Roughest - Final section of Bandit at Movie Park Germany. I've never jackhammered for an entire hill section before..

Smoothest - Lech Coaster @ Legendia

Roughest - Cyclone @ Coney Island Luna Park (Despite being a really fun and enjoyable ride)

Smoothest probably Air or Swarm, although Swarm has gained a bit of a rattle now on the back row.
Roughest is either Colossus back row or wild mouse at blackpool.
