Are Premier water coasters smooth?

I was just wondering because they look like fun.

Warning!: If I'm cranky...tell me and I'll blame it on hormomes.

Ive never been on one but they are proboly as smooth as the shoot the shoot water ride built by Intamin.

You know Titan Fan, that dosn't really answer his question a whole lot.
