I occasionaly do camera work, and I always put my slider behind my head. This allowes for far better glide and swoops. Had 1 occassion on which the camera got stuck for a moment on the slider, not comfortable, but could clear it with moving my head. But this is during flight, if I have a mall I cutaway my main (off course) and if nescesarry the helmet. Personally I think a camera helmet should always be able to cutaway, this is also why I don't like the bonehead flat-top, has anyone a solution for this? Whatver you do, get a helmet you can cutaway!
