Helmets
It's been a while since we've had a thread about helmets, so I figured I'd start one. I did a search on the forums, but there are so many threads out there with so many different recommendations that I'm not seeing the forest from the trees anymore. Maybe if I specify my requirements and keep it base-specific, somebody has some advice.
I've been using my N-Vertigo freefly helmet so far, mainly because I hesitate to add another helmet to my collection. I have helmets for skydiving, bicycling, motorcycling, climbing and skiing. Arg....

I realize that this helmet is not going to provide much protection on hard impact though, so it's time for something better.
I need the following:
1. Good solid strength and protection. More than just protection against bumping your head in the plane. Ideally some proven strength through a CE or other certification program. I care more about protection than weight.
2. Good visibility, including full peripheral vision. No visor, or at least a detachable one.
3. Chin protection, preferably one that is slightly protruding, so it stops your face from deforming.
4. I have no interest in video at the moment, but I'm guessing that some day I will succumb to the lure, so future camera-attachability would be a nice-to-have. However, if I find a better helmet without this, I'd take that one.
I have my eyes on the Bonehead Illusion at the moment. Does anybody have any comments on it? My main worry is their strength, since they don't seem to go through independent certification testing.
Thanks,
Jaap
