Unit

Is Unit Slab good with Gotham Narrow?

Forums: 

I was thinking of pairing [[http://www.typography.com/fonts/font_inside.php?wipID=19&productLineID=1...|Gotham Narrow]] and [[http://klim.co.nz/unitslab_info.php|Unit Slab]]together for a magazine. Stylish but serious. I may also use them in print for a book that accompanies the magazine's branding.

Two questions:

1) Are these a good match?

2) If you had to pick a simple typeface (serif) for the book's body text, what would you choose?

Thanks!
