On my tourer, which has a longer reach than the "light" bike, the bars are about the same height as the saddle. With the shorter reach "light" bike, the saddle is about 5cm higher than the bars.
I can use the drops (shallow) for extended periods on either bike.
My "hybrid" MTB has the saddle much higher than the bars despite a steep rise stem and upswept bars. It's not as comfortable as either of the other bikes.
At the back of my mind is a plan to put a new, uncut, fork on the MTB and fit drops; I reckon that higher bars will compensate for the longer reach.
