Quick question... I am curious how many spikes per magnet pass John's SSG build's generally use. I have watched all the youtube videos I could find and my EFV DVD's for clues, even turned up my volume to listen to try and hear his SSG's when he runs them.

I'm trying to draw comparisons with my own SSG. After quite a bit of testing mine works better with 2 spikes (haven't been able to get 3 out of it), so it made me wonder if his builds utilize multiple spikes to reach the impressive COP's.
