I feel ya on the slippery slope. If you seen the first rendition of this coil.... lol. I found a very long term hobby. Since I posted I have ran into a 12/30 setup on pupman for capable 42" spark I will try out eventually. But I still am stuck on the thought of lots of windings. When does the number of turns become overkill? I hear 800 to 1000, or 8 to 12, and seemingly universal no matter size. Then I read about 1600 for low power. Is there some good reading or a good explanation on this?
