I built a secondary using Litz wire once (in my early coil building
days). No significant difference in performance or Q was noted over
using a suitable gauge of solid Cu. Litz is usually specified as
being most useful in the MW broadcast band where the higher frequency
(smaller) coils operate but by the time you approach 500kHz to 1MHz
you find that more inductance is better than more Q, at least for
disruptive discharge coils.
