On topic, I rode Hulk Monday.
My ride on Rockit was rougher, actually. I got stuck on the lift hill and really got to see some pretty cool things like the new light effect and the strobes at the end, as well as where the ride launches. My ride was without sound, so it was quite freaky not knowing when it will launch.
And it was my hundredth ride on the Hulk!! I do agree it should be refurbished for aesthetic purposes, but the roughness lies, I'm pretty sure, in the vehicles themselves.
