All else being equal, I'd avoid a helmet with lots of "aero" points out the back. Besides looks (I don't think the multi-pointed helmets look good), I've read that the points can potentially catch on the ground and increase the risk of neck injuries. I agree that fit is of more importance than most other factors. Though my neck occasionally gets tired on long rides and I'm prone to overheating, so I do value weight and ventilation. I confess that it's been several years since my last helmet purchase (my current helmet was a freebie/gift), so I'm not up to speed on current helmet offerings and not able suggest a specific model. That said, next time I need to buy a new helmet, I'm going to look into a MIPS helmet: MIPS | Patented Brain Protection System
