I guess the argument therefore is that you don’t need MIPS for a helmet to have some degree of efficacy, but still nobody can categorically say there are zero benefits from MIPS for mitigating rotational injuries so it’s all still a bit ‘meh’ really.
I still think fit and comfort (and to some extent cost) take precedence, you’re less likely to take a tumble in the first place if you’re not cooking your brain or have a lump poking into the side of your noggin.
So MIPS isn’t something I would go out of my way to have, others will want to hedge their bets which is fine I suppose.
Plus I have plenty of hair and from looking at my Dad I don’t think baldness is on the cards any time soon so nature has gifted me a consistent shear layer anyway 😉
