Real, Voyage at opening was not *that* smooth...I've seen the reverse POV taken before or at opening.
I know you haven't been on Piraten, but I also know most steel Intamins I've ridden have a bit of a rattle, so consider that the ride is probably not at the very top level of steel coaster smoothness. I'm guessing it's likely average for new steel rides you've ridden. It just happened to be the best reverse POV I could find quickly...or at least the most similar in setup to Voyage's reverse POV.
Now I don't want you to look at the camera shake...that's because the camera is not mounted like it is on the Voyage video. I'd like you to pay attention to rider body motions, which in the end is most important anyways. I'm not even discussing hard and intentional transitions, because I know you're not...I'm talking about tracking. What I'd like you to notice is the smooth body motions in relation to the bouncing throughout most of Voyage.
Maybe you're exaggerating for effect, not sure, but I don't think that statement holds any truth. Yes, it may have been very smooth for a wooden coaster...that I don't doubt. But I believe it was never as smooth as an average new steel coaster, and I think those two videos very clearly support my thoughts.
