Fair note: Dominator was built on a swamp with awkward terrain. There's a reason why some footers are taller than others, and it isn't because KD has varying terrain in that area.
I don't know why the kink is there in the loop, and I don't know if it was there when it was built in Geauga Lake. I can tell you, however, that Dominator is a heck of a lot smoother than Hydra at Dorney Park.
