The ride typically rolls back only in the morning while they are testing, unlike Dragster, which I saw rolling back with park guests quite frequently.
After 4 rollbacks between 9:15 and 9:30 am, I never saw it rollback throughout the day, even after it went down for repairs.
It's going to be down for at least a couple weeks, but it's definately worth a visit, especially if you're into Intamin coasters as much as I am.
There's a ton of parks within a few hours drive worth hitting. just make sure you get a q-bot for Kingda Ka.
Thanks for the kind words on the video.
