This year, Paris-Roubaix was won with a bike that was designed for fat tires and a higher bar position...the classic design features of a "touring bike". The winning cyclist said "If I am comfortable, I can ride faster".
In other words, unless you are in a short time-trial on a smooth road going 35 mph, don't obsess about an extreme "aero" position.
That isn't true. All it takes is experimenting with positions on a flat road with a powermeter. With the same power, you'll find a noticable change of speed just switching bewteen the hoods and drops even going as slow as 15 mph.
