Hi Dave,
 
I too use lightning arrestors on the HV side.  They are simple and handle
anything we can throw at them.  After all they are designed to handle lightning
strikes.  What are the voltage ratings on the ones you use?  I have not run any
tests to see where they really clip.  Have you? 
 
All mine are salvaged and very cheap.  I always have my eye out for them and
grab them when ever possible.  For me they really solve a problem robustly and
easily.  Of course, I have protective filters on the low voltage side.
