I reluctantly figured this one out many years ago. After riding nothing but road bikes 40 years I just could not get down on the drops and my butt in the air. For me it was a big change. I ended up lowering my seat few 2cm and raising my stem 3cm. After multiple try's with swept back and straight bars I gave the bull horns a try. That was the ticket. So I now go for Bull Horn handle bars with bar end break levers.

Note: I use friction shifters on the down tube so your shifters and break set up have allot to do with what you go to.
