I've had more than my fair share of "OHMYGODI'MGOINGDOWNHEADFIRSTAGAINARRGGGHHH!!!" crashes, including, ohh, 3-4 wrecked helmets. Never had the slightest problem with peaks though.
As far as I can tell, if the peak hurts you in a crash, it was a poor quality, ameteur crash with not anwhere near enough committment or lack of skill that would otherwise ping said peak off into the distance or shatter it completely, along with your helmet, in a proper fast, hard stack.
I suggest therefore, if that is your problem, to use more speed, less brakes, and less skill to crash harder, to avoid this happening.
