My $.02..went from Shoei to Scorpion to Arai in the last 5 yrs. Was a long time Shoei guy, but got a deal on a Scorp and it fit well, but the face shield mechanism workmanship left a lot to be desired. Love my Arai, but am looking to replace it with the RS-1 after a conversation with Nathan. Shoeis seem to be a little heaftier than the Arai and Bell, but quieter than the Arai for sure. Then again, at the track with ear plugs in, that's kind of irrelevant.
