I think the overbank is taller than the full-full.
The video is pretty crazy. The first drop seems to have more than a full rotation. The first raven also seems to have more than a single rotation, as well.
If the first drop is ~260~ feet, and the IRT is also @ 200 feet, then there should be plenty of 'oomph' to get the cars through a whole bunch of extra spins as it travels through the course. I guess we'll know soon enough.
