I've done it, but I guess technically this is a touring bike, I ride this bike most often. I used a flat bar, cut the width to sort of between a mountain bike width and a road drop bar width, added bar ends for multiple hand positions but laid them down to an almost flat position to mimic the road bar portion going out to brake hoods. I very much like this setup, and also have a road bike with drops so it isn't a drops verse road thing. I'd like to try the Koga Denham bars as well.
