Woohoo from Missouri! Sounds like after you find your new "A" and "B" packs, you should use the "A" to take Paul (and Ben) up on their race challenge - of course after you secretly install the Zilla 1K that you are going to secretly buy "for the conversion that ISN'T on a budget."
Kidding aside, it would be good to see just how different 72 and 48 volts are. Which reminds me: I still haven't gone through Mullet's thread, because Paul made me fear... I mean, I've got to recover from the late nights staring at this stupid computer screen. Maybe we could have a 4-way race: YouTube and all!
