I'm using ITC Kabel as a headline font and I'm looking for a font for the body copy that would complement it nicely. The body uses italic and roman and the type will be reversed on a dark background. So, it seems like a sans serif font would be more legible but, I don't want to use kabel for copy and I'm not sure about using two sans serif font's together.

What do you think about using two sans serif font on the same piece?

If I should stick with a serif font, what would be most legible reversed out?
