I'm seriously tempted to get the nailed-head one ... they look cool.
On the subject of lids, I trooped around several LBS's to try the various different makes and models on and settled on three in the end. Budget narrowed it down to two, and comfort decided the rest.
Incidentally, the one I'd decided on
before I set out was dropped in the first 10 mins. as it was completely the wrong feel / fit. I thought it
looked cool, but it just didn't work.
I did end up spending more than I'd set out to though (
three figures), but it was worth it as I just couldn't
feel the helmet when I was wearing it. Really light, really comfortable.
It's still going strong 4 years down the line, and still feels as comfy.
Cheers,
Shaun
