I'm working on a new brand identity for my software company, and after some research we've reached a consensus that Fontsmith's Hackney (http://www.fontsmith.com/fonts/fs-hackney.cfm) could work well for us.
It has a technical look which I hope will give technical papers credibility and authority, but it's also nice and round so doesn't come across as geeky and esoteric as other technical-looking faces (Eurostile et al).
My question is a pragmatic one. Should I use Hackney for body text or choose something less stylised? I've played around setting some documents (Hackney is available to test free on Fondeck), and at smaller sizes Hackney feels cluttered in the body and needs a lot of tweaking in the tracking etc. Is that just par for the course with a very stylised font, and I should suck it up and work a little harder? Or would a more sensible body sans be worth looking at? If so, what should I look for?
