My bars are actually slightly above my seat, and they're very wide bars (nitto noodles). I ride in the drops about 20% of the time, just because I can stretch out, flex my back, put a different sort of pressure on my arms, and to absorb shock better.

What I like most about riding in the drops is how much better the seat feels. It's fine all the time, but when I'm in the drops I can tell it's more like how the seat should fit. I also find myself more powerful on long flat, and I can feel later that I used different muscles if I ride in the drops more than on the bars.

I know it's counterintuitive, but I also like to go up hills in the drops, to a certain point. I don't know why.
