It may work well to use a small sphere for the bottom unit, and a
regular toroid for the top. THe small sphere has such a large ROC
that it should prevent all breakout from the lower areas. What might
even be better is a thick (large ROC) but small toroid at the bottom.
I had good results with the sphere in my "capability of small thin-wire
The thick toroid would be better than the sphere from a practical
standpoint due to its flat top and bottom.
I agree that a good quality, large ROC topload is needed for the
bottom unit in any case.
