No suggestions for a new bar, but take a look at your setup before buying new ones. One reason that you see a lot of shallow drop bars is the current trend to use a lot of saddle to bar drop, so you're more aerodynamic with your hands on the brake hoods - where most riders spend most of their time (even the pros). I see a lot of bikes setup with only a few centimeters of drop from the saddle to the top of the bars. Try something in the 7-11cm range, but only make changes a little at a time. I used 9cm of drop for many years and made the jump to 11cm with no problem - switched from a -6 degree stem to a -17.
