Hi Gary,

As long as you have a good connection, it doesn't matter much how the
connection is made.  This part of a coil is just not that critical.  I
how large a coil you are making, but of course as the coil becomes
(4kW +) the connection becomes more critical.  I've used all different
methods including many times just a clip lead on small (up to 2kW)
coils, and
it just didn't make any difference in the output spark length.  If it's
small coil, I suggest that you do a test; first try a good connection,
up the coil and measure the spark length, then replace the good
using a simple clip lead, and re-measure, and I don't think you'll see
difference in spark length.  In theory, a good connection is always
in practice often no difference can be seen.

Looking for reality in coiling,
