TC frequencies aren't all that high, so the skin depth is pretty thick,
perhaps more than the diameter of the wire.  I'd say that solid wire would
allow you to get more copper in a given space.. That is, a 10 AWG solid wire
will be smaller OD than a 10 AWG stranded wire. Also, from a corona
suppression standpoint, particularly with respect to turn-to-turn arcing,
solid wire might have a larger radius of curvature (although, bundles of
small wires have fairly large electrical radius, comparable to the physical
radius, so on that basis, for a given gauge, you'd want stranded...)

All in all, I'll bet it makes little or no difference (maybe 5%?).  Wind it
with what you got.
