How fast are the flips. I've known about this effect for maybe a couple of decades, but never heard any theories on how fast the flip is.

If the flip is really slow, then that seems to lead to less human catastrophe, but more difficult perhaps for other species?

The problem with the flips is that they go hand-in-hand with a dramatic weakening of the magnetic field until the new orientation is established. During that time solar storms are not deflected as well and vulnerable electronics will be fried.

If my new tv gets fried during the apocalypse I'm going to be pissed.
