I had an Arai Signet GTR, and now I have a Shark RSi. I went to the Shark because the Arai Profile wasn't oval enough and pushed on my forehead. Loved the Signet, love the shark even more. Absolutely refuses to fog. Light as a feather. Fits long oval heads excellent. I won't wear a modular helmet as helmet weight plays a big factor into fatigue. webbikeworld is a great place for helmet reviews. Bad thing about the shark is limited support from local shops, at least around here. They aren't stocked.
