I've been watching POV videos of both sides as this coaster looks like it is right on my borderline of ok vs. not ok for me. Velocicoaster is the same for me as well, which I've been on once and would ride again but only on days that I'm feeling more adventurous.I've heard some say that is more intense than VC and others say not quite, but very close. I wonder if it depends on which side you ride because one is apparently more intense than the other (although I've also heard people flip flopping on which one).
There is apparently a lot of air time though so you should love it.
On Velocicoaster, I absolutely loved the first half which I think much of Stardust Racers would be similar to? But then the tallest hill on Velocicoaster was too much for me, and I struggled a bit with the barrel rolls.
Looking at POVs of Stardust, it doesn't seem to have any super tall hills. I think I'd be fine until closer to the end where the barrel rolls start: Can someone verify - it looks like there is 1 maybe two barrel rolls that start at the top of a hill and roll as you go down?? Do both sides do this or does one side have barrel rolls closer to the ground than the other? I'm a little concerned with that first roll especially, and it's hard for me to tell from the POV videos exactly what it is doing. (or are these even barrel rolls??)
