I've never ever considered the Hulk to be rough. But with all this talk about the back portion being the worst, and mentioning 'whiplash', I'm thinking maybe my definition of roughness is different. I consider rough to be bumpy, which I have never thought the Hulk to be (in any row, at any point in the ride). Now if we're talking the back portion, I would actually say it's smoother because it goes slower, but the sharp turns and quick maneuvers don't really make it 'rough' per se. In fact, I like the quick directional changes, it gives the ride some spice. In any case, if that's the problem, sitting more towards the front will alleviate that problem. Other than that, I can't see how anyone thinks the ride is rough, as in bumpy or jerky.
