i ride motocross and nowadays most tracks wont let you ride without a neckbrace, i love them and couldnt see riding without them. I would never wear one skiing and i do doubles... so coming from another person paraniod about breaking my neck, i say you are fine. If you are throwing inverts, you should know what the hell you are doing... aka throw it in powder first! i landed most inverts first try in pow, there isnt much of a reason to wear a neckbrace skiing, to break your neck you have to overshoot the largest jump in your park and land right on the centre of your head, that is very hard to do!
