Well, I have an HJC CL-15 in cherry red to match the bike. I'm seriously considering getting a safety orange helmet for my next one. HJC is a decent middle of the road brand. But like I said, each helmet and manufacturer will have a different shaped mold they use for their helmets, from round to pointy to flat. You really have to try stuff on.
Take a look at NewEnough. They have a great return policy and could probably help you out by shipping numerous helmets to try on. Narrow it down to roughly the correct size and get a couple different brands. It'll cost you a bit with the shipping, but worth it getting a properly fitted helmet.
