I think they all differ. Because of the different diameters, there might not be a way to do a 90 degree portion of one of them - because the way the track sections might be cut to form the turn.
I have the High Bank2 and you can use 3 sections to do 90 degrees, but be aware that the lead up to and exit out of the banks are usually 3 track pieces before being flat again.
