I have 40cm 3T Aeronovas (36cm at the hoods). Super comfortable, very long reach. crazy flexy.
Also have 38cm Zipp SL70. Much stiffer, much shorter reach, pretty comfortable too, but doesn't cradle your wrists like the aeronovas.
I'm not an IAB person but with the narrow bars, your elbows are inside your hips anyway and you can get a pretty dialed position and actually take corners hot without having to move your hands back and forth.
Downside to both is internal cable routing. Bleh.
