<<<<Group,
         Just had a couple of quick questions.  The first question 
is:  when constructing a strike object, should it be tied to  RF ground, or 
should it be connected to a separate ground rod in earth?  My second 
question is regarding the "Terry filter".  What are the purpose of the 
MOV's in the circuit?  Is it just a safe guard in case a capacitor shorts 
out?  Will leaving them out make much of difference functionally?  Just 
thought I would check before making a Digi-key purchase!  Thanks everyone 
in advance!

As far as I know a “strike object” can be anything…. Grounded or not
All of mine seem to behave more or less the same. But a grounded one might 
be best.
My coils strike all sorts of things, metal, non-metal. I once observed that 
a NON grounded Aluminum sphere (hanging on 2 feet of fishing line) was hit 
more often than the grounded rod.

Just Zap a bunch of stuff and see what works.  It’ll be fun.

Good luck
Josh
