I certainly am not qualified to state what helmet features are better (or not better) for avoiding concussions - I'll leave that to the helmet brands. Leatt prescribes to Kali's softer-foam-philosophy and I think that makes a lot of sense - even to this layman - since passing CPSC standards are really about helmet durability in a crash v. impact absorption. But I can't back that up with mathing or sciencing.
In terms of the chin bar, I'll go on record as thinking they're always a net help over hindrance. I've met a few people who had brutal concussion after smoking their jaws (helmets totally fine) never mind broken jaws, broken teeth, etc and I've never seen anything that would have me believe that wearing an open lid is a safer option (though certainly more comfortable in many situations).
