There are a lot of flat bars. I don't get it. I guess people don't like to sprint at all, because I just can't develop the kind of power out of a flat bar as I can from drops or especially bull horns. Plus I have a couple of different positions that I use for cruising and I would lose the shoulders of the bar if I put on a flat bar.
I've actually been thinking about putting drops on my mountain bike. Take it back to its yoot (it's an old Bridgestone).
