hi everyone,

would a 15\30 nst be good enoughto run a 6"
using a static gap and mmc or should i stick to
a 4" or 5"
i also have acsess to 160mm(6.3"), 220mm(8.7"),
280mm(11.0"), 440mm(17.3") highly polished
stainless steel spheres about 0.020" thick.
i would like to be able to use one of these for a
topload or am i better off sticking to a toroid.
