Yeah, I thought Zeus was the smoothest of all the coasters in the Dells, actually.
smooth- Goliath at La Ronde, Definitely. Mummy @ USH next.
rough- cyclone @ sfne's pretty bad. But really fun.
I dont understand XLC being rough. I rode it in its last days, and its first or second year. It was fine both times, in front and back. Hmm
XLC was rough to me in that it was really bouncy. It didn't hurt but it tracked really awful. It also had the worst brakes ever, in my opinion. And my last ride on Cyclone was really amazing. Airtime everywhere, and I'd almost call it smooth (definitely aggressive though). I've said it before, if not for those damn trims at the end, it would probably be top 3-5 for me based on that last ride.
