True , helium finds ways to leak like no other gas (it's the smallest moloecule around). Thats why we leak check O2 systems with it. Nitrogen on the other hand has one of the lowest rates of expansion when heated or cooled. It's also cheap and inflammable. I know a few guys have put it in their tires to keep them from going flat when it hits -35 here in Canada.
