I was thinking of http://en.wikipedia.org/wiki/Damping_ratio rather than http://en.wikipedia.org/wiki/Damping_factor Is there an understanding of why high "damping factor" would be good? Jont's findings suggest otherwise (I believe he's saying the current is typically more relevant than the volage).
