I've always had decent luck with piano wire from the hobby shops, 
available in a variety of sizes from rod down to nearly a hair if you 
get serious.  You can break out the Dremel and cut a "bit" on the end 
to help out.   I have a lot of Rochester H carbs on hand, always 
manage to turn up what I need for whatever.  Difficult problem 
children can get a soak in a can of lacquer thinner for a month to 
aid their cooperation.

I have a double-end pin vise I use at work with piano wire probes in 
each end, been using it for years on circuit boards.  Piano wire is 
some fairly tough stuff.
