I'm not sure what you mean, "it adds an extr 3-4 inches to your head"? My proteus doesn't even cover my whole head. There's usually about 3-4 inches of my head still left even though the visor is on.I used to play with my visor on, but then removed it for one simple reason: it adds an extra 3-4 inches to your head, that will be seen way before you can get your eyes around a barricade. It also helps you sit a little tighter, no visor banging into things. Actually, I don't think anyone but our back players use them.
