My choice is the Shark. I love it, not cheap but. supposed to meet EU racing standards, because a lock for the chin, if you did not catch that feature (push in to lock). If, for ever reason you want to use it as a 3/4, it stills good as in the video. I use as a 3/4 for funeral escort and maybe riding around town on hot days. To be honest, I have been out on the freeway with the bar back, no buffeting or anything like that. Some modulars can not be ridden over 25 or so with bar back.
The internal, slide up sun shade should be a feature on any helmet. Riding n the Blue Ridge, nice sunny day----nice very dark tunnel, one hand slide, clear vision. I am not a mail order fan. I want to make sure the helmet fits.
Any helmet is better then none. Yes, over the last 60 plus years of riding, I have seen a few survive crashes without a helmet, but I have seen lots more that lived or suffered way less injuries because of a helmet. Take a tomato outside and slide it on the pavement. Enough said. It should your choice however, no big brother.
Why do I push for helmets and safe gear ? No pics, but about a hundred mile a hour slide down a black top road in a outlaw race many years ago. My BSA Gold Star did not do well. My helmet would called a 3/4 now, but "jet Style" in those days (top of the line then). Bubble shield on front had a hole worn through it. Foam core visible in more then one place on helmet Leather jacket and pants shreded all to pot, USAF issued "jump Boots" about the same. I kind of hobbled away with no major injuries
