Ah Jim .... certainly, I could perform such a series of experiments and might draw conclusions from them that could truly be significant or at the very least, be valid. However, I know a fellow who has made hundreds of these items in a variety of forms and so it seemed logical to me to simply ask him if he has ever noticed any significant differences in what actually works best, rather than going about reinventing the wheel myself.

Guess I was wrong about that.
