Hi Tiger, and welcome to TN!
In answer to your question, I was just saying earlier today that I love rough coasters, but only woodies. The more rattling banging and lurching it does the better.
I don't like rough steel coasters though because they can be very uncomfortable, particularly with over the shoulder restraints where your ears get a pounding.
To use an example, the old Arrow Corkscrew at Alton Towers is horrendous, it really is about time that pulled it down and put something else there.
Psyclone, on the other hand at SFMM, was great. I loved how much it threw you about. I do know, though, that we're in the minority on this so be prepared!!
