Companion for Exemplar?

I’ve fallen in love with Exemplar and am going to use it for my latest site.

I’m considering either using it as a display font for logo, menu, etc and pairing it up with something else for the body of the site, but it works well at small sizes too. I’ve never used the same font family for a whole website - what are people’s feelings on this? Alternatively, can anyone suggest something that would go nicely with it? I’m finding it hard to match with anything else.

Thanks
