My most painful ride has to have been on Hercules at Dorney. If you don't lean forwad it just kills your back. This is 1000 times more voilent than Mean Streak.
For a flat ride my vote goes to my favorite the Flyers at Knoebels. The next day after several good snapping ride my lower back is sore for several days. Still the best flat ride on the planet. :)
