As someone who skated through the 90's and on, helmets just weren't a big part of our culture. It wasn't until X-Games started making everything bigger for television that helmets were deemed necessary for skateboarding. Never have I ever owned a skate helmet until I bought a Onewheel... And I hated it lol. (Yes, it was Triple 8.) No ventilation, clumsy fit, uncomfortable and top heavy.
Didn't see my brand on the tested list but I use IXS for mountain biking so naturally transferred to Onewheeling too. Recently bought a FF and love it even more than the half shell. Seems to duct in air more effectively, still super light weight and all the certifications.
