The aerodynamics seem to work just fine as my head remains in a safe a secure riding position at 70-80mph. I have only taken my bike up to 80mph so I can not comment to higher speeds.
In my opinion, the issue is in the wind noise that increases dramatically over 55mph. I ride in an upright position. If you ride in a tuck position I suppose the noise might not be an issue..
Lastly, the EXO750 does come with a locking mechanism for the face shield. It does work but not as smoothly as when I first bought it. I have about 800 miles on the helmet and I do take care of my equipment.
If you can save up a few extra dollars I'd consider a better built helmet. I am in the process of an upgrade now.
