Then don't buy one. Is it great to have choices or what?

Having had MIPS helmets and non MIPS helmets and seeing first hand that it's a virtual certainty that it will not cause harm over regular helmets and after seeing first hand the absolute horror of a serious TBI, I think it's a worthwhile bet to make. And that's why I'm spending the money to outfit my family accordingly. If I'm wrong, the incremental cost to me for the whole family is $0 to $100 max. If I'm right and if circumstances occurred that it prevents a serious TBI, then I'd say the marginal difference was pretty much priceless. That's a bet I'm happy to take all day long and twice on Sundays. Little downside to stepping up, big upside if it's needed and it works.
