That's funny because Hit Me With Your Best Shot is the one I would say is the least intense for me. It is the only one where I am not shaky on my feet for a few minutes when I get off the ride. Everyone has a different perception I guess.
I've had both Free Ride and I Want You Back. I can't remember whether it was Free Ride or I Want You Back that made DD swear to never get on it again- and she drew blood where her fingers were digging into DH during the ride. I think it may have been "I Want You Back" It felt like the drops went on forever. It really felt like more drops than any other time we had ridden it.
