Thanks guys, this helps out a lot. With the argument about fashion vs. functionality, I realize that it would be pretty ridiculous to die because the device meant to save your life was actually a P.O.S. that gouged your eyes out at 60. I've definitely decided against getting a helmet like that.
Now I need to learn how to do stuff like this on my own, because I REALLY wanna cosplay as my Halo: Reach Spartan III.
That, of course, comes after Sheik and a bubonic plague doctor.
