I do a mixture of road (e.g. psychopathic car racing on the way to the veg market) and trail (local deer park - grass, gravel and wooded paths) riding on my MTB. I currently have a helmet like this but I don't feel like it offers my head much protection. Because of the style it feels perched atop my skull, and seeing as one of these days the grumpy toffs I piss off by daring to ride on 'their' road will knock me off, I kinda want my skull to remain intact.
I'm considering a lid like this, as (in my mind) it offers more protection and if I do get smashed, it'll hold my brain in. I am however somewhat conscious of looking too 'down with the kids' if I wear one of these.
Any opinions on the relative merits/safety of each? Am I just being a bit mad?
