one more thing, in most cases, "wire size" should always be the
largest you
can get away with (have handy, etc)--not only is it more efficient
(lower
ohmic loss of power) it usually holds form better... I would not be
all
that concerned about capacitance between turns--unless for very high
freq
use...

John, have you ever tried winding the largest possible wire around a
ferrite toroid ring?
