I have the equivalent of Wavies, Ahearne MAP bars, on my upright CX bike made into a poor-man's Hillborne - this is an easy 60-mi bike.
The upright wide-grip position makes a huge parachute, so I added Nitto double lamp bracket and mountain bar ends.
This gives a roadie aero/ core-muscle position and slices the wind as well as any road bike.
I will always remain a fan of Moustache/ Albastache, as long as you set up the reach properly using accurate stem reach measurement
(50-60-mm closer stem reach than you ride on road bike).
The wide hoods are the aero position, and beyond comfy.
