I just can't quite take to them. I wear full armour most of the time, but the neck brace, to me, seems like overkill. Granted I'm no lightning quick racer, but no slouch either. It's a pretty expensive (overpriced) singular piece of equipment, and yes obviously you'd rather pay whatever than be a quadraplegic, but i don't see what they would do seriously except for maybe help reduce a little whiplash here or there. If you had a serious crash I don't think a neck brace would be the difference between say a broken neck, spinal compression etc or not. So 600 odd dollars to possibly lessen a bit of whiplash here or there? i don't think so. I've had a couple of slams on the chest/chin where the front wheel washes out over the top of a berm and i've gone down hard, and the chest plate (and obviously full face helmet) was what i was glad to be wearing. and actually, if i was wearing a neck brace at those times, i may well have ended up with a fractured sternum as you hear a bit about. Also, if the rearward movement of my head was restricted, would that increase the severity of the impact on the chin? To me they're something you might wear if you're going hell for leather and wanting to wear every piece of protection you can get your hands on, but to be honest i don't understand why people wear them as their sole piece of armour. There's a far greater chance of taking some sreious bark off your arms or other incidents where body armour would save some nasty abrasions or more, just seems like far more of a priority to cover your arms/legs than wear a neck brace. To me.
