Hrant, a pretty bold move pairing two slabs...

I usually pair serif heading with sans body, or vice versa. If you really need to go with a serif, how about Caslon?

Egyptians were originally (early 19th century) the bold for Scotch, which makes sense as a pairing, because unless your accompanying serif has high contrast, there isn’t sufficient distinction between one serif face and the other.

However, if your display face is a bold Egyptian, you can use just about any serif style for body text.
