Brad,

You won't see any difference in spark length using a PVC form
compared to an acrylic form.  The difference in loss is not
significant.    I can't see how you can have only
about 800 turns of 28awg wire on a 22"  form.  I have about 1300
turns of 28awg wire on a 23" form.  I'm assuming you're using
magnet wire.  If you're using PVC insulated wire, that's a different
story.  Maybe you have quite a distance where there's no wire
at each end of the form making the actual winding less
considerably less than 22".  I seem to remember that 800 turns
is only *about* 12" of winding length with 28awg magnet wire.
