Wow!

Thats some pretty intensive testing!  I really have not had much problems 
with it firing my safety gap.  If i dont have to install a strike ring, then 
i do not want to, that would further limit my sparks.  Hopefully, when i 
finish all of my plans that i have for this coil project(oh, and im getting 
quite ambitious) i will have some pics that Terry could put up somewhere on 
his site.
