Fox Flux MIPS - how's the fit compare to...

[FastforaSlowGuy]

My wife's getting ready to pull the trigger on a new Fox Flux MIPS, but due to some major schedule limitations that prevent her from hitting the LBS, she's buying online to have it delivered in time for a ride she has planned. She's generally worn Bell and POC road helmets, and I was hoping someone here might be able to weigh in on whether the Fox fits similarly shaped heads.
