Thanks for the tips Joit.
I built a few Bedini SGs and I remember having to wind the coils a certain way. With these particular coils, the polarity is going to be flipping back and forth so orientation isn't quite as critical. Nevertheless, one direction will be harder to switch than the other, so orientation may help there.
I also have a Pulse Width Modulator that I'm going to use to explore the effects of different frequencies and duty cycles. I hooked up an IGBT on the output to drive the coil and it works pretty good.
The trick will be to find an optimal frequency and pulse duration. The higher the frequency, the higher the output power will be. Switching the flux thoroughly and efficiently is going to take some study. Domains don't switch quickly unless persuaded in no uncertain terms.
