Don't forget to consider the helmet you wear too. Some come too low on your brow or are too far away from your forehead and block the view making you have to lift your head higher. Visors can do the same thing.
Some helmets have various ways to make the helmet sit further back on your head. Check inside them and see if there is adjustment for how the cradle (can't think of the proper name) fits your head. Not just the little wheel you spin on the back to tighten the band.
