They're great masks and I love mine, but with masks it's more about preference and (imo anyway) face size/shape. If you have a skinny/small face, e-vents are perfect. If you have a really big round head you might want to look at some JT proflex's or something of that ilk, as e-vents can leave fatfaces a bit exposed on the jawline. Great mask though, go for it.
Oh yeah, since you mention headgear in your title, I might suggest getting a headband or sandana. It might seem pointless to you now, but having been shot in the forehead many a time, I'll say that they take the worst of the sting out, and if you get cosy with eve from eden headgear you can get some pretty sexy ones.
