Is it possible for them to be "too good?"

Expect one in the mail in a couple days.

A hi-pot test on both caps would be cool.  Do you have the ability to 
perform di/dt or dV/dt tests?

I had figured the test was simply connecting the cap to the power supply 
and cranking up the juice!  Guess I was a little off on that!

Thanks again for all your testing,
