My current consideration is: big enough current, low loss (high efficiency), high frequency (how high? several MHz?).

On the subject of Torroidal cores, does anyone know the answer to this? Isn't it possible to increase the inductance by stacking cores and using the same number of turns? Effectively doubling the inductance?
