On friday at six flags, the line for iw was short, but it took forever to get to the ride due to the fact that the yellow harnesses were being replaced on the second train. The first train is done, and they are very nice, but i had the worst ride i have ever had on this day, hit my head a lot, and it was very rough. Also, vu is running really well and fast, the only rough spot i found was on top of the first part of the boomerang both times i went on it.
