Probe Design

So I found a PDF in the files of our group here showing how
a 3-rod/6-ball contact probe works.

Stainless is suggested for all the contacts. Wouldn't gold be better?
I'm having visions of getting weird looks if I show up at the walmart
jewelry counter with a micrometer and try to measure the roundness of
cheap gold-plated ball-shaped earings...

Actually, if I go with gold I will probably order the stuff from rio
grande or another jewelry supplier so as to get gold-plated brass (aka
gold-filled) rod for the other part of the contact pair..
