I would personally put the strike conductor at RF ground if you use it.
Or better yet, listen to what Dr. R. mentioned about simply some
strategically placed rf ground rods. I would likely go this route simply
because it's easy to use or not use. The floating point is still a point
of contact just like the primary (no difference there). Whichever one is
closer to any given spark event will get hit.
I do like acrylic discs over the primary. Making a round cut out of
acrylic is really easy. I took a 1 meter long metal ruler and drilled
holes every inch. I hook the center end to the center of the disc and
then insert a cutting bit in the ruler holes (any hardened steel that
scribes the acrylic). I simply scribe a rounded hole at whatever
diameter I desire. It helps to scribe on both sides of the acrylic for a
nice clean break. A little sand paper to the cut edges and you have a
nice disc. I don't use thick acrylic (usually about 1/8" thick is plenty).
